One of the more common struggles I witness while coaching slalom skiing is how to manage control of the handle and body position throughout the edge-change process.
Many skiers make the mistake of combining the release of the handle with the edge-change. What achieves greater results is separating the two... the edge change should occur somewhere close to the center of the wakes, while the release of the handle should be done about half way out to the width of the buoy from the center of the wakes.
What you're looking to accomplish is maintaining a hip-to-elbows/handle relationship that stays the same all the way from the completion of the turn, through the wake crossing, and up to the release (again, about half way out to the buoy from the center of the wakes). As you complete the turn feel your hips and your handle come together. You should be able to feel your elbows pinned against the sides of your vest. If you have any gap at all between your vest and your elbows, then your position is not as strong as it could be. As you approach the wakes soften your legs, and allow the load you have built up through the cut to release the ski from its cutting edge on to its inside, turning edge. The key here is to keep your body's core tight. Maintain your position of the hips, the handle, and the elbows. The only body position change here is in the lower body. With your ski on the inside edge, ride it out halfway to the buoy's width. This is where you can start your handle release. Allow your self to ski out, and away from the handle.
By maintaining this strong body position through the edge change, and waiting longer to release the handle you will set yourself up for much earlier, wider turns.
