Typhoon When I went back to Trackman though, it spun 1000 rpm’s more than the others and I lost 7 yards of carry.
This is the reason you should not fit anyone that is a really good player into graphite, unless they are getting the correct numbers. Absolutely no gain, no purpose, unless they would be like me and just want 'the looks'. I've never found any graphite to 'flex' for me as one would think, until I go to A flex; thus they feel 'hard' to me as most steel does. Even then, I sometimes add head weight to get the 'feel' and flex I want. KBS Tour 90 shafts & those Nippon shafts are steel shafts I've found that actually feel softer than any graphite.
I don't know much about fitting, except for myself. I know what I want to 'feel', and numbers be damned; they mean nothing to my swing. I'm not going to lose a lot of distance nor am I going to gain.
People talk about having physical problems and want graphite. I don't see anything in using them that is going to help. Like you found, the tips of graphite can be heavy and that will lead to the same feel as steel, imo. There are many products that can be used with steel to take away the 'sting' as some call it. You can still get vibrations with graphite as you get from steel. When I pulled the shafts from a couple of the Apex heads(steel) they had rubber inserts in them much like a weight; same shape, same lengths. TM irons have similar I've found. I've not looked around the internet to see if they are available to the public, which they should be.
So, given same weight, I'd always choose steel over graphite. I'm back to using steel mainly now myself. Nothing heavy though, 90-105. And they feel soft sometimes.
The thing with soft or hard stepping....don't you change flex point at some point, raise/lower? Which may change ball flight, and spin rates? I don't know, never studied that. Maybe Scott can weigh in.
