SMT What is the first thing that a golfer does when picking a club out of the rack?
When I bought my 1st set, wayyyyy back when, I went into every local golf store or any place that sold golf clubs back then. I proceeded to manhandle every set of irons in each store. Went back around to a few of them 2-3 times before finally settling on the set I bought. That set of 1st Flight irons had the perfect 'feel' in every club.
Not about flex as I had no idea of such things nor about weight as I was working daily throwing around (up to) 120# hydraulic cylinders.
All about balance......feel.😉
