Description The Babolat RPM blast is the premier model in the polyester. The string is a firm, stiff, and durable especially in this 15L version. Even though technically classified as a co-polyester, from the feedback we have received the stiffness and playability is to a much stiffer string. Loved best by big hitters from the baseline that like to use spin to move opponents side to side.We find it to be more useful as lower tensions, not a good choice for players with arm troubles. Composition: Co-Polyester. Octogonal cross-section String Type: Monofilament Pro Players: Rafael Nadal, Jo-Wilfried Tsonga, Samantha Stosur
