Haven't hit these in years but looking at trade and have been playing Recoil F3s but should OK now and can beef up a bit but driver swing speed down to 90 and remember the ZZs playing stiffish. Sound about right? Probably should pass but thought I would get input.
It's definitely lighter than the S400 - it's the shaft the CFS was based off of. it was one of the shafts we tried to knock some spin off with. It's like an S+.If I remember correctly the ZZ65 is basically a Dynamic Gold S400 shaft.
