I have to give a big tip of the hat to NatRobin here. He suggested the FST 125 stepped shaft (S/X).
I had one, and also a Dynalite R/S, so I decided to profile them. They are darn near identical, including the weight.
I use a 460g profiling weight I cobbled together, not the official 454g profiling weight. So they will be a little off from any official profile you might come across. Plus it was only one sample shaft of each. Here are the CPM's at various beam lengths (the amount sticking out of the 5 inch clamp).
Inches of beam 36..31..26..21..16..11
FST 125 202..234..274..329..433..643
Dynalite 203..232..271..327..427..647
Doesn't get much better than that. What happens after tip trimming is up to the clubmaker. I'll have to post this on WRX for searchable posterity. Thanks again Nat!
