MSV Focus Hex is a recent arrival from Germany. As the name implies, the string is hex shaped for added spin potential. Excellent tension maintenance for a poly string and not bad in the comfort dept either. Available in 1.10, 1.18 and 1.23mm.

Forten Aramid Gear. This is a Kevlar hybrid with textured main strings to enhance spin. The mains have a core of Kevlar surrounded by a nylon jacket that is cross sectionally shaped like a gear. The crosses are synthetic gut. For big hitters looking for added spin

Same as Super Smash Honey except with added texture. So far, only in 1.25mm (17ga).

Same as Luxilon Alu Power but with added texture. Roger Federer uses this one in a hybrid set with natural gut main strings, in what I would call a "reverse" hybrid. The idea is to mute the power of the gut without having to use ultra high tensions that would shrink the size of the sweetspot.

$29

Signum Pro Tornado 1.23. This heptagonally shaped polyester is one of Signum's new Black Line of strings. Designed to produce big spin.

$30

Babolat RPM Blast. New co-poly from Babolat that is softer than their earlier offerings and octagonally shaped for more spin. Currently being used by Nadal, Roddick and Tsonga. Available in both 16 and 17 ga.
