think bowed legs is the worst as an waterskier cos you tend to ski more and more back on the ski when you get the power from boat down your hips thru your legs, that forces the leg to bends more outwards until a dolphin can jump between your legs, the more you bend them the more you gonna sit and ski only on you rear. @skibrain knock kneed maybe the best, who knows maybe better than normal aligned legs!
its only the rear thats raised 0,5 inch so i can get my rear hip more over the front of the ski both are the same 7 degree.
the hardware screws that are stainless from HD store (expensive cry) pushes binding plate down quite hard so i think its ok.
i think all that have an tendency to ride the tail and have knees that arent tucked inwards center line ski and together 100% on the water should try this
