Only thing I use now. It is thicker, 12.9 vs 12.75. But that’s not the only difference, different taper too. It’s more of a straight taper vs a pro-taper. It’s kind of like the z shaft taper. I ended up turning mine down just a bit, 12,75.
Plays stiff, more feel, lower deflection than the 314 by a ton, firm hit.
