What happens when Ya lean forward "AND" bend your knees ?
Seams like that would edge the board more and force the tows into the deck ??
Remember "My" ankles are made of SS.
The logic is that by leaning forward (which forces you to bend your knees) you do drive the toe side edge in harder, but that grip combined with enough power through the kite is what enables you to hold a course. Not sure how that will work with your legs though mate...do your ankles flex or are they set at an angle that cannot be changed?
