These strings have a lot of power, control, and feel. They have a similar feel to Babolat RPM Blast but with a little more comfort and half the price. I strung it on my Wilson Steam 99s - which has a very open string pattern - and popped very early (2 weeks). Overall a great string with feel and power.
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.
