I agree on the 07 75. Once powered its nice. But days when its marginal it feels a bit sticky and it is not as loose on the wave either. I have one left tricked out with thrusters if you wanna try. For big waves and offshore the 07 might be better, but for anything else I think the 08 is better.
The 70 is super sweet regardless of year. My favourite is the 07. The 08 is similar but a tad thicker which might be good for you but is unnecessary for a lightweight like me.
