I carry two racquets in my bag - a BLX Pro Open and a 6.1 95. I usually use the Pro Open, but if I'm playing with a fairly hard hitter I'll often swap to the 95. The idea is that with the 95 I can control the ball better and don't need as much power from the racquet when the ball is coming at me fast.
If you play by the rules some might consider you a *. If that's a problem then, by all means, give away as many points as necessary for their approval
