idk what your coach was saying, you need to be fairly agressive right behind the boat, skiing the hips to the handle, and have a nice early edge change, but keeping the hands on the handle, that gets you too the bouy, staying patient and keeping you vision down course should lead to a good one ball, i try to ski my 32 just like my 28, its easy to over ski 32 iv found, by working too hard, pulling too long or not enough
