Signum Pro's Topspin SF features the same "SuperFlex" technology that makes the Ultra Power SF a powerful and lively string. This lively and textured synthetic gut plays soft and does equally well as a full set or as a hybrid with any Signum co-poly.

This string really shines in hybrid with co-poly strings. It makes for a durable and playable cross string. The string itself is 16ga, but when measured the textured crosses cause it to have a reading in size much thinker than it actually plays.
