@Dirt. Thanks
@jaredH20, I have an early 2010 and it is a 66. It feels like the same stable ride I am used to with some added platform to keep me up. It feels a bit quicker and if I get forward at the ball and stick the tip in, it is not folding me up at the knees like my 66.
I moved the DFT to .758 last night and it was better but the second set I moved it to .765 and it was great.
I will stay at .765, 6.845 tips, 2.501 for the weekend.
