As someone who has tried to "force" or control the wrist snap in various sports in the past, I can tell you that in my opinion and experience it is much better to develop a stroke or swing where the wrist snap, if any, happens automatically and naturally. Much more consistent that way, don't have to rely on your timing being perfect every time you play. Think of a golf swing, you setup everything so that the wrist snap happens naturally at the proper place in the swing, would be very difficult to try to control that in the few milliseconds you have before impact.
Keeping your grip loose and your wrist in a natural position will enable your wrist to add power to the shot naturally, and I believe the shorter backswing will help promote a good accelerating stroke.
