Chinny O' - When you do your cutback - think the back hand needs to slide along the boom to meet the front hand. This will depower the sail, put your body closer to the mast, allow you to surf the board around on the rail & just maybe avoid some of those wipeouts(?)
My 2 cents worth for what it's worth 
(Actually 
, why am I giving you beta when you thrash me every year in the Cannonball Run?!
)
