TOM I am sorry but to my knowledge there is no data out there to tell you what the COR of any driver is. Most companies do try to make their conforming drivers so that they would not be over 0.830 COR when the face thickness is at the thinner limit of the +/ tolerance. Due to every driver in history being subject to normal +/- tolerances, there is no possible way to know what any driver you actually buy will be in terms of its COR. But the range would not be all that much since a change of… Read more »

RAY The players who are properly fit into the higher lofts of the 13 and 15.5 driver heads will have lower clubhead speeds than those properly fit into the 9 or 11 loft models. This is because in proper loft fitting the slower the clubhead speed, the more loft is needed to properly elevate the shot to maximize carry distance plus roll for most distance. Players with slower clubhead speeds can have a little more of an issue rotating the face back around to be square at impact and can tend to leave the face a little open. This is… Read more »

JJ The clubmakers are all independent business people which means they all can run their businesses differently. Because the essence of what they do is purely custom clubmaking based from fitting golfers, every club they build is different, tailored to each golfer. So the prospect of Demos is not all that great because what if the shaft, length, swingweight, loft, etc, is not what YOU need. You hit that demo and don’t like it and you form an incorrect conclusion about the club because it doesn’t fit YOU. Some of the clubmakers do work with special devices called connectors that… Read more »

Steve On its own, flex does not contribute one thing to clubhead speed. It’s main contribution is to launch angle/spin and shot height and shape of the shot with respect to landing angle and best combination of carry + roll. And then very much, there is a contribution to shaft feel in terms of how well it matches to the golfer’s preferred sense of bending feel in a shaft – if the golfer does have such a preference. Many do not. That right there is how a shaft can contribute to swing speed. If the golfer over time has developed… Read more »

Lincoln We’re in a bit of a transition phase with regard to many of our models going forward. Much of that transition into retiring some and introducing new models has been “monkey wrenched” (delayed) a bit due to the effects of the pandemic on the factories and supply chain issues so the timing of this is a bit affected. For now the LH models are the 929 and EQ1 woods, the EQ1 hybrids, 979 irons, 771 irons, PCF Micro Pro wedges. The 919 LH driver got whacked when we were working on different new things with the 919 that also… Read more »

Andrew Wow, thanks so much for taking the time to not just take a good look at our product line in a thorough manner, but also for stopping by the comments section to share your experience with the models and shafts that you had the chance to hit. I’m humbled and honored by your comments. And to everyone else who may see this, no, I did not in anyway solicit this!! HA! However, I do have to be totally honest and say that it does not surprise me that you were able to find the models could out perform any… Read more »

Steve There is no question that DEPENDING ON YOUR ANGLE OF ATTACK (downward vs upward vs level), as clubhead speed drops, driver loft should increase to enable the ball to stay in the air longer to achieve better carry distance. The key is to get the ball to fly high enough so it does that, but not so high that the ball cannot achieve decent roll to enhance the total distance. CLubhead speed is just one part of this loft decision making process. Your angle of attack is the other and I would think with Ed’s experience he will be… Read more »

Dave Cold won’t adversely affect anything on the golf clubs themselves. You won’t do any damage to the clubs by playing when it is cold. Depending on the type of grip you have on the clubs, very cold weather will make the grips feel firmer/harder but it won’t cause any damage to them. I would recommend that you never store your golf balls where it is cold because they will be affected and you would notice a difference in performance and mainly in the impact feel of the ball. Keep the balls warm and when you play, try to keep… Read more »

DAVE Very pleased to hear that you like both the 919 and 519 and that you do notice differences in the two. That’s precisely what we had in mind when I did the 519 to follow on the 919. Now we hope down the road when it comes out, the number in between those two will get positive reviews as well!! Shhhhh. HA! Not enough is known by people outside of Taylor Made about this new Stealth driver. There are foundry people who insist there is a thin titanium face behind the composite material, such that it may not be… Read more »

David The GRT reduced vertical roll is fine for speeds up to 120-125, or at least in the >10 yrs that we have been making the 919, we’ve never once heard of or seen any situation in which a player of your velocity had any issues with it. What you may want to check since you have had this for a few years is whether you may have started to cave in the face a little bit. Titanium driver faces do have a life expectancy and especially if you with your 120mph speed have been playing with this for 2+… Read more »

Pat The absolute most rediculous thing that all of the other golf equipment companies do is to continue to sell their drivers with a standard off the rack length between 45 and 46 inches. I’ve worked on fitting research aimed at this for over 20 yrs now and fortunately the majority of clubmakers that work with my designs do understand this and rarely to never fit anyone with a 45″ length. Most never go over 44″ and end up around 43-43.5″ for most of the custom fit drivers they fit and make for golfers. The results are obvious – way… Read more »

David Yes, absolutely, that is one of the primary functions of the bendable hosel. You will need a way to clamp/secure the head to enable bending. Few of the usual loft and lie bending machines have this capability since most are developed to bend irons only. But a few out there can accommodate drivers/woods/hybrids for bending. Once clamped, for a more open FA, you bend the hosel in the direction away from the face, as if you are bending the hosel backward, away from the target. The CP4 hosel is soft, it bends with about the same effort as any… Read more »

DAVE I think Bryson is finding out that his 190-200+mph ball speeds is pushing the threshold of performance and known face performance dynamics for drivers that are made the way they are. I believe this could have been seen with the long drive guys except for the fact no one thinks anything odd when they see a long drive guy hit one that just goes off the planet. Everyone thinks that it is a really bad swing brought about by trying to swing that hard. And most of those off the planet long drive shots probably are. But with a… Read more »

TOM You can if desired, shorten the 9 and wedges by removing the grip and trimming off however much you wish to shorten these clubs. I would recommend doing that gradually, starting with taking off 1/2″ and seeing how that goes. If you still feel there is a lack of consistency because they are still a little too long, then take another half inch. Do keep in mind that for each half inch you shorten the clubs, they will lose 3 swingweight points and from that, can definitely swing with too little head feel for your swing timing and rhythm.… Read more »

Tom As one with severe hearing loss who has spent a LOT of time investigating sound (and the lack of it!!) I can definitely tell you that one man’s “ping” sound can easily be another man’s “click” or “thud” sound, because of the big differences in how human ears along with the brain works to process sound. I can tell you that in the several years that the 365’s have been out, I personally have not corresponded nor heard from anyone who said the impact sound was different in any way that could be perceived by some as being deleterious… Read more »

Gary Not until loft increases to a point of 26 to 27* (combined with a normal Angle of Attack) will you see a high COR face begin to measurably drop below the maximum possible smash factor allowed by the limit on spring face conformity in the rules of golf. First of all, for a driver (or any clubhead with a loft under 26*) with a 257 CT/0.830 COR face, the max smash factor you can get is 1.495. Because all launch monitors have +/- tolerances for picking up clubhead speed and ball speed, you will see an occasional max 257CT/0.83… Read more »

Gary Neither. The last biased driver I designed was believe it or not, back in the mid 1990s, a driver head I designed for Golfsmith called the ACCU CORE 50 with a 45g brass weight embedded in the heel side of the head. Since then I have never done any sort of bias design of weighting in ANY head I have created – at least until next year when there will be a new driver that will be capable of being either draw, neutral or fade biased. The 919 is designed with a CP4 titanium hosel which is a pure… Read more »

KURT Thanks for stopping by! Yes, I remember your Grandfather Ken. I do remember corresponding with him over the years. Good for you that you kept one of the clubs he made. Wow, the 360cc version of the 915CFE was our very first line of woods from back in 2002 when we started the company! The main thing that a larger size head brings is a higher MOI to reduce the amount of head twisting and energy loss when you hit one off center. But really, if a driver has a really well engineered variable thickness face (slightly thicker center… Read more »

Mike
Yes. When the head is ordered from Diamond Golf, you can ask for them to bend it before they ship it and they will do that. The 919 is made with a special CP4 grade titanium hosel so it can be bent 4* in any direction – up, flat, open, closed. So your preferred 54* lie is within that range.
TOM

KURT Standard off the rack clubs made by the big companies don’t do a very good job of accommodating MOST golfers, not just shorter golfers. You might find 1 to 2% of all golfers who could be compatible with the 45 to 46″ length of std made drivers and that’s just one thing. It is good to hear you are working with John because he is VERY experienced and knowledgeable from many years of working with golfers. I’ve known him for a long time in this business and I know you are in good hands working with him. I am… Read more »

Nathan You would have to contact Mondher or Aimen at golfmechanix.com directly to ask them to make the back clamp piece for the bending machine they make for this to be able to secure the drivers and woods/hybrids for bending. These molded clamps were always made with hardening putty and never were made with any type of softer, rubber type material. We just always used a thin sheet of rubber you can get from any supplier like Grainger or MSC in between the putty clamp and the back of the clubhead to prevent any marring of the head, and that… Read more »

Juergen Thank you so much for coming to our website and posting a comment!! Also MANY thanks for having chosen to work with Mike – he is without question one of the very, very best and most knowledgeable clubmaker clubfitters on the entire planet. And your club at Jakobsberg is truly a nice facility and a wonderful place to spend a day. I have had the pleasure of being there 4 or 5 times over the years to teach clubfitting seminars for clubmakers or for the German PGA and I never get tired of the visit because it is so… Read more »

DON Hmmmm. . . now where would you have heard something like that??!! Hmmmm. . . . . mum’s the word but I can say that being in semi retirement with no responsibility for the day to day operations of a business means I can be messing around with a LOT of new things !!!!! ;>) Maybe. . . . . but I can assure you that no way, and I mean NO WAY, can I design a different driver that can be any better than the 919 for ball speed and off center hit performance. It just can’t be… Read more »
