Well my graphite experiment failed. I got a set with the wrong shafts. The online description said "regular". The shafts have an "R", but they are 4.5 which I've learned are senior flex. Anyway, the plan now is to do a fitting with my pro. That's probably what I should have done in the first place. I was trying to save a few bucks by buying preowned.
Hopefully I can sell the set I bought since I'm past the thirty day return date. Thank goodness I kept my JPX 850s with steel shafts.
Bummer man!! Don’t let that discourage you, do the fitting and keep on tinkering away. It becomes just a way life after a while!
