First suggestion would be to post this in the wakesurfing section of the forum... a lot more surfers post there.
Second would be to make sure your weight is all on the RHS, including the weight in the front. It's all about "list".
My set up is typically 750 in the back, center locker full and another 700 up front all on the RHS. Make sure you're in deep water too, makes all the difference.
