I really enjoy playing with Volkl Cyclone. It definitely assists in dialing in my shots. Absolutely loved it in the Volkl Organix 7 310g! That combo really up'd my game - control, precision, heavy shots. It's quite comfortable and at $7.99 it's a good deal. The only negative is that it looses tension pretty quickly (2-3 weeks for me) but about on par for a poly in my experience. I don't string my own racquets so if I were to pull it out right away, I'd lose the savings Volkl provides with its lower cost.
