I believe I want to make sure there is no gap between the palm pad and racquet (grip is too loose) as it moves into the collapse phase... As suggested, I am placing coins in the palm to check that they do not fall out during the swing.
Take a dime and put it between teh index pad (or heel pad) and racquet with the continental.
