Don't know how many people here remember Kwun's thread about the pinky grip, it is basically holding the racquet w/ your ring finger and pinky while the other fingers are loosely wrapped around the handle. This way, when you swing, the racquet itself moves within your hand and adds more power to your hit. By having a smaller grip, the movement of the racquet is enhanced and I guess that's why smaller grip equates to more power.

Another grip-related advice I got was to wrap the bottom of your handle extra thick, almost twice as thick as the rest of the handle. This will give you a little more feel + control of the racquet when you are holding so far down the handle w/ only 2-3 fingers tightly. Hope this helps.
last time i tried that the racquet flew out of my hands
