  1. Thank you so much, Mr. Wishon. I just looked at the video of his swing and you’re right on the money with his swing. He loaded so much behind the ball at top position so he moves his head slightly forward toward the target and his head is just about 2″-3″ behind the ball at impact. Thank you for the knowledge and the valuable time. Have a wonderful and blessed day.

  2. Dear Mr. Wishon,
    My son has a driver SS between 115-118 mph. We noticed that the angle of attack is about 1.8-2.5* negative. I was told that the shaft that would benefit him the most would be a shaft with El profile of stiff butt, soft mid, and very stiff tip in order to reduce his back spin, as his back spin is in the 3200 range. He’s hitting them between 295-310 yards, but his fairway hit average is between 10-12 out of 14 per round, so we don’t really want to change it. He is using the Fujikura Rombax Z7z08 in X stiff with Titleist 915D3 8.5* head set at 9*. Any recommendation for another shaft that will benefit him more. I am thinking about the Ahina 72X, Rogue Max 75 X, Rogue Silver or perhaps the Tour Green X flex in 70 grams range.

      There are many things that could be discussed about your son’s shot performance, which I will be happy to do. However, in all honesty, the results he is getting with his current driver are quite good and very competitive with other players of his age so I would first say that you really do not need to change anything. But I will offer some comments. First of all, you did not say what brand and model of launch monitor was used to record his spin of 3200 rpms. You also did not say whether he was hitting range balls or actual top brand balls to get these launch monitor results. VERY few launch monitors can read backspin accurately. Only TrackMan and Flight Scope are reliable for that. Second, if he is hitting range balls to get this spin information, that means the spin is not typical of what he would get using the real balls he plays with.

      Changing a shaft just to change the spin is not a smart thing to do for a very good, high speed player. The only way a shaft change can reduce spin is when the shaft is either stiffer overall than the shaft the player is currently using, OR, when the tip section of the shaft is stiffer than the shaft the player is using. With no good empirical data on a wide variety of shafts, it is a guess as to whether any of the shafts you list are stiffer overall or stiffer in the tip section than what he has. Given the fact he is hitting a lot of fairways for how long he hits the ball, you would be taking a VERY big and VERY expensive risk to keep trying any of these other shafts. It would simply be a trial and error process.

      And for what gain. In truth, WAY TOO MUCH EMPHASIS is put on the spin measurements of a driver. Given the fact that so many people hit range balls on a non TrackMan or Flight Scope launch monitor, for most players, seeing a higher spin is unreliable information. What you have to do to determine if a player really has a spin problem is to watch the shape of the shot. Shots that fly with too much damaging spin tend to curve upward quite high and drop more straight down with much less roll after landing. In addition, any player who has a negative angle of attack with the driver automatically is going to see a little more spin on his shots. You cannot avoid that unless you either, 1) use less loft on the driver or, 2) take lessons to change the angle of attack from negative to at least level or slightly upward. And number 2 is VERY risky because any swing change could cause problems with the high percentage of fairways hit.

      So my recommendation is truly to leave things as they are. If you change shafts you just will not see very much difference at all, especially given the fact that your son has a slight negative angle of attack with his driver. 99% of all golfers would be very envious of being able to hit 10-12 fairways at 295-305 yards with their driver. Tell him to go practice putting because that is truly where the low scores are made.

    • Dear Mr. Wishon,
      First of all, thank you so much for your time and prompt response. I collected the data from EBC at PGA National in west palm beach, where they had him hit 14 drives between 2 flags about 35 yards wide, and didn’t even charge us for anything. They use Trackman and Titleist ProV1X, which happens to be the same ball my son is currently using, for the data collection. We live in Texas and although the back spin may have resulted in some of the yardage loss, the ball still roll here in Texas. We competed in a tournament in FL and everything stopped on the land. During the week that we competed, his average drive was only 280-285. His iron shafts also ballooned as he’s gained 5″ in 1 year and SS went from 108-118 in 1 year, and we have not changed his shaft. He’s working really hard and I just want to make sure I get him the equipments that can perform according to his performance. We noticed a lot of purely striked shots fell straight out of the sky for 20 yards short during the tournament in FL and blew all the lead after a first round 67 at the Champion course. Again, thank you very much for your time. I really appreciate all the knowledge. Here are his equipment now;

      Driver: Titleist 915D3 with Fujikura Rombax Z 7z08
      3 Wood: Titleist 915F with Fujikura Pro Tour 83 X
      Iron (3-PW): 2014 Taylormade Tour Preferred MB with ProjectX 6.5 Flighted
      Wedge (50,54,58): Taylormade 2014 Tour Preferred with True Temper Spinner Wedge+

      The only 2 clubs that performed well for him were the fairway wood and the putter. He actually hit his 3 wood almost as long as his driver during the tournament.
      Thank you.

      Based on your additional information, I have to say that it sounds like your son needs to be working with a GOOD teacher to reduce that negative angle of attack into the ball. The fact that you say the shot shape is “ballooning” and falling short and falling straight down is indeed an indication of too much spin which is almost always coming from being too steep into the ball. If your son chooses to work with a teacher to change his angle of attack, you will have to expect that there will be some time in the process in which he does not play as well as he did. Ballooning shots, especially in the irons, are a swing issue and almost never an equipment matter. If it were me, since I know how hard it is to make a major swing change, what I would tell you son is to just begin to think about keeping his head behind the ball when the clubhead comes into impact. If there is no forward movement of the body and the head on the downswing, it is much more difficult for the club to come into the ball on a very negative angle of attack. Keeping the head well behind the ball coming into impact can help shallow out the angle of attack, and that is not a big swing change to do.

      Hope this helps,
      TOM
