Conscious control of the racquet needs to be maintained within the backswing. There are a few ways that players can do this: hold a penny or other coin in the palm when you serve. Unless you have a very sweaty hand, the coin will usually fall to the ground if you switch grips on the backswing. Just having the coin in your hand is usually enough to help a player maintain conscious feel of the grip.
