WOW! Excellent reply, definatly worth the wait thanks for taking the time and effort Ian.
I seriously thought about the 5.7 it works for my friend who let me try his but he is only 70kg for me it just wasn't quite enough.
Yeah I know of the great wind range I can get from Blades maybe I could get away with a 6.2 blade, I'm most tempted by this option to keep the same feel, less brain power(anxiety and time wasting of what sail to rig)and I'm after more wave sailing than freeride.
I imagine the Gator's will have similar bottom end to the Blades.
