Popular at the highest levels of tennis, this is a TW staff favorite for spin. The slick surface of RPM Blast allows the main strings to slide out of alignment, grab the ball and then snap back to add extra RPMs to your shot.  Though RPM Blast offers a slightly softer feel than traditional polyesters, it is by no means the softest co-poly available. It is an ideal choice for big hitters with heavier racquets seeking maximum control, durability, and spin. (And it seemed to work quite well for Rafa!)
