rsvman2 Is it age, per se, or is it mostly about swingspeed?
More about mid iron club head speed, transition time and release early-mid-late. Eample when I check playing length/lie I start with TLT 4i/hy, 7i and PW in each series and shaft profiles and weights. They are built light so I can add lead tape. I check impact as lead tape weight is added. Ever seen a big golf store do that? I you do that's the store to buy from if they do all the other fitting factors correctly. There is a huge difference between fitting and fitting. LOL
I have never seen a big golf store check other than club head speed they are about the bells and whistles of spin numbers on a simulator indoors which most never swing indoors as we do outdoors. Part of the major brand huckstering. Never check impact on club head, never change heft match to see how impact differs etc etc. Big golf stores are about 20 mins. with a potential customer and move on. These are many of the reasons Joe and Jane Hacker are buffaloed from the start.
