Signum Pro Tornado 17

A 7-sided Poly that grips the ball producing huge amounts of spin.  Crisp, clean hitting with lots of control.  Yet it is a string that needs no time to get used to.  Players find it so easy to control just after a few hits.

This string is ideal for big hitting baseline players who want both spin and power from a durable string.  The co-polyester formulation increases elasticity for greater comfort and power.

It has become one of my go-to strings of all time.
