Well, to start my question I will give some background information. I play with a ncode 90 strung at 60 with luxilon ace 18, however, I still get an amzing amount of power (a little too much for me), I use an exteme eastern to semi-western grip for my forehand and an eastern grip for my 1handed backhand. So i was fooling around the other day and i realized that I could control the power of the racket by choking up on the racket handle, so I started to hold the racket with the heel of my palm about .5-1 inch from the butt of the racket. I found that this really gave me more control with my shots and i didn't feel as "clumsy" when hitting some shots. My question is, are there any disadvantages to choking up on the racket (besides the obvious reduction of length and power), and is this advisable for someone who has a little too much power like me?
