What flex is a JZ shaft?
I was thinking of reshafting with Dynamic Gold shafts . . . . The JZ shaft (and any other Ping shaft without specific flex designation) is somewhere between Stiff and Regular. It wasn’t until late in the production run of Zing2s that there was a differentiation in the flexes of JZ shafts. With that said, the JZ is lighter that a DGS or a Rifle, so changing the shaft will change the feel of the club. Only you can determine the playability but unless you are under thirty and still get over 110 on your driver speed you might rethink the S400/DGS reshaft. The lighter shaft promotes more speed. The JZ tends to hit the ball slightly lower than other Ping shafts I’ve tried. One last thing for you to consider: The new CSL shaft from Ping is, in my opinion, the best proprietary shaft Ping has used since the ZZ-Lite of the late ’80s. The CSL is a true lightweight steel shaft. While it retains the .355 tapered tip, it has a .600 butt and seems to have better torque resistance than older Ping shaf
