I find it odd noone has commented here. Tom! Tell me a bit about these irons. The weight bores to adjust swing weight are absolutely fantastic! I’ve done a set of your irons before with just the hosel ports and those were wonderful. What can you tell me about these? Would you classify these as game improvement? Looking forward to hearing from you and about these beauties!

Ps gotta say it again I really LOVE the weight bores to adjust the swing weight. It baffles me that more people haven’t realized how helpful this is.
