get a better fin, unfortunatelly . had the sam eproblem with i101, tried all sort of combinations with stock fins and they all were semi-solution. finally invested in custom fin and the board was a whole new story in all type of conditions.
heard it somewhere on the beach...why does not starboard deliver boards without fins but with a custom made boarbag (for each model)? would be the same expense but boardbag would certainly work as opposed to stock fins that are proven year on year as ...crappy semi-solution
