I have both. The 314/2 comes stock at about 12.7 and the Z2 comes in at 11.75. I had the 314/2 cut to 12.50. The Z2 is supposed to be a lower deflection shaft than the 314 but I don't notice much difference. I play mainly with the Z2 but can pick up the 314 and play just as good. They are pretty unforgiving; if you are a little off you will see it but I"ve gotten comfortable with both.
