What is meant by stability of a racquet? I never realised this before (throughout most of the 8 years I've used my H tour) but sometimes when I try to hit a forehand, I feel the grip twist out of my hand. To clarify, I use a SW forehand grip but sometimes as I make contact, the grip would move into an eastern forehand grip. Now going back to my question, what exactly is meant by stability? Could this unwanted grip-switching be caused by the fact that I use a smaller grip than "recommended"? I've grown up using this racquet with a grip size of 4 3/8th or L3. I have pretty gigantic hands and 4 5/8th or larger would be the "recommended" grip. Any comments or input would be very helpful thanks!
