RE: Question for Isonic 101
I'm no slalom expert, far from it, but I have an iS101 whcih I play with sometimes. I've used sails up to 7.5 and its absolutely no problems. I even think you can go quite a lot bigger without loosing effectiveness. I've used my 7.5 with both the 40 and 34cm fins, the 40 for light wind and upwind easy and the 34 for high wind and more speed oriented sessions. I'm about 150lbs.
