I'm just a weekend warrior, but I believe simple things like keeping your hands down, slight bend of your forward knee/ pressure and standing proud for lack of better words, will help. As a free skier for a lot of years and skiing with lots of same type guys I notice that they want to ride the back of the ski, skiing slower and deeper in the water, kind of a security blanket, i sometimes find myself doing this, I look at it like I don't trust my ski to hold the edge in the turns when in fact it turns way better and faster.
