This Babolat RPM Blast 1.25 200m features a co-polyester mono-filament (with an octagonal profile and cross-linked silicone coating). Even though the RPM Blast offers a slightly softer feel than traditional polyester. It is by no means the softest co-poly available. It is also an octagonal cross-section, the coarse structure, and the mesh silicone all maximize your racket's spin.

This is a suited and perfect choice for the modern player who likes to take full cuts at the ball. It is an ideal choice for big hitters with heavier racquets seeking maximum control, durability, and spin.
