I am stuck between purchasing one of these two rackets. I've owned the 6.1 for awhile, but the grip size is just too large for my hand. I tried out the Pure Storm Ltd. and found it to be an excellent racket, especially with its low swingweight, but I had trouble generating spin due to its 18x20 string pattern. Many of my shots sailed out of the court, but the ones that landed in were flawless. As for the Wilson, I feel that its sheer weight forces me to practice proper form, however, when I get tired after several sets, I find that I begin pulling up on my arm, straining my neck to keep the ball in play. The spin provided by the 6.1, however, far exceeds that of the Pure Storm Ltd., and, though I lack some control with the former (again, due to it's heaviness and lack of proper grip size), with work I could bring the heat with either racket. Any thoughts? I'm not new to tennis, I've played some four years now, and I'm in excellent physical condition.
