Recently, I've bought myself an isonic 101 of 2009. Coudn't try it out yet, much too cold. I'm real curious about that thing with cambered versus non-cambered sails. I have a 7.5 cambered V8 of NP and a 6.3 non-cambered free-ride sail that I want to use on it. Many people already told me to get a new 6.x cambered race sail for it. No one can exactly explain why that is. Well soon I will find out.
