L-Tec 4ST Helix 12m String

L-Tec 4ST string

A real surprise when it was first launched, the 4ST string remains a benchmark in terms of comfort and power. The string is a copolymer with a pentagonal profile and a textured surface, which gives the ball plenty of spin.

The result is a muffled ball-strike that's devilishly effective at setting the pace in rallies. The unique 1.28 mm gauge is an excellent compromise between power and control.

Careful installation of the 4ST is highly recommended to maintain a good tension hold throughout the life of this string.
