Unlike most conventional hybrids, the DTAC Revolution NT Hybrid is comprised of two co-polys. It offers an impressive combination of spin and control along with phenomenal durability. Featuring a shaped co-poly main string, this hybrid grabs the ball very tightly. The round co-poly cross string allows the main string to slide further out of position so that it can snap back with more force. The result is MASSIVE spin! The low friction between main and cross strings also extends the life and playability of the stringbed. Try this 1.26/1.25 version for slightly more spin and feel than the 1.35/1.30 version.
