I’ve hit a lot of golf clubs in my 39 years of playing. I played alot of quality Mizuno stuff in my earlier years and have gravitated towards TM stuff after I decided that I didn’t need to be hitting my MP33s any longer. I remember hitting a playing partner’s Callaway X-16 on a par three one time and I could hardly feel a thing and it flew a long way. Six months ago, after deciding that I wanted to try some irons with more modern lofts, I bought a used set a Callaway XR16s. Same thing. Couldn’t feel much. Sent them back to Cally Pre-owned.
I’d bet the pros are chasing feel as much as anything.
