So, I made up a club yesterday using an old "ladies flex" shaft. I wanted to see how it felt to swing a soft shaft club as opposed to a stiff flex that I usually swing. The results kinda floored me. I took 3 7 irons to the driving range and started hitting.
So there's a tree at 150 meters on the range that I normally aim at and with the stiff shafted club I noticed that with a goodish contact I'd reach the tree ....no problems. BUT, if I got it a bit skinny or a bit crappy I'd be 10 or 15 short. Also if I nailed it it would fly to 165.
With the ladies flex I noticed that with a skinny, clunky contact I got a lower, still strong shot that landed at about 145. but with a good average contact I got 150. And with those real strong contacts that previously just flew and flew with the stiff shaft, the soft flex club seemed to go higher but dropped consistently at 155. No matter how hard I hit the soft shaft club 155 meters was IT.
this little test has got me thinking. I didn't really notice much dispersion difference between the soft club and the stiff club(but I'm sure there would be) but there was a big dispersion difference between the 2 clubs in terms of distance. no matter how hard I hit the soft club I couldn't get it past 155. The stiff club seemed to have a much greater length dispersion than the softy. I also had the feeling that the softy was "helping" me on those poor contacts.
So if reducing dispersion on the shorter irons is important maybe I need to err on the soft side of shaft selection.
