I put a Graphite Design PM702 stiff in mine and it was super straight. The .350 is a bit of a problem but if you shim a .335 it is fine. the stock shaft was a little light and weak for my liking and the PM702 dropped the spin rate and cut down the dispersion. I swing between 107-112 and usually launch around high 13* to 14*. (i did have to put the weights in a high neutral position to get bring the launch up a little)
hope it helps,
