RE: I-SONIC 101
It's the same feeling that early in the season a guy spoke about with me. "Scccaaaaaaaaaary" but really fast. In flat water it helps you to better control the board when really overpowered,in rough chop,I think,you need no scary attitude (please note that it's impersonal advice),strong legs,big sail,soft and lifty fin,footstraps and mast base far back. When all those typo are right trimmed then the 101 becomes a truly warrior.All its fantastic attitudes comes out.
If you think at it from a racer point of view it's easy,necessary and not a problem.If you watch at it from a week end warrior point of view keeping the 100% out always it gets a bit more difficult.
