MSV Focus Hex . German made string and as the name implies the string is hex shaped for added spin potential. Excellent tension maintenance for a polyester string and not bad in the comfort dept either. Available in 1.10 and 1.18mm

$22

MSV Heptatwist is similar in feel to Focus Hex but is seven sided and twisted to impart even more spin. Very similar to Solinco's Barb Wire. In black in both 1.20mm and 1.25mm.

$22

Weiss Cannon Silverstring . Similar in feel to Luxilon's Fluoro, this co-poly string provides easy access to spin and a cushioned response at an unbeatable price. In 1.20mm and 1.25mm.

$23

Signum Pro Poly Plasma 1.18, 1.23 and 1.28mm diameters. Poly Plasma is a bright orange co-poly that has better than average tension maintenance for a poly based string and plays a bit softer than Luxilon.

$24

Tecnifibre Pro Redcode 17. A comfort oriented co-poly with a lively response and a wallet friendly price. Not as stiff as Razor Code and not as soft as Black Code.

$24

Solinco Confidential officially was released in 2020 after a couple years of "confidential" testing. Stiffer than Hyper G but not as stiff as Tour Bite, it's a good choice for advanced players looking for a control oriented poly. For now, in 17 gauge only.

$26

Solinco Hyper G is one of the more recent offerings from Solinco and is considerably softer than Tour Bite which preceded it by a couple years. In 16 (1.30mm), 16L (1.25mm), 17 (1.20mm) and 18 (1.15mm), the string is fluorescent green and pentagonally shaped. Solinco also offers an even softer version of this called (what else?) "Hyper-G Soft" which I am carrying in 17 ga only.

Solinco Tour Bite is a pentagonally shaped polyester string made in Taiwan. It is designed for big spin. Available in 1.05, 1.10, 1.15, 1.20, 1.25 and 1.30mm diameters.

$26

Head Hawk 17. Another polyester monofilament for you hard hitting topspinners out there. Pretty low powered for a poly so if you can generate your own pace this is one you might want to try. In 17 ga only.

$27

Tecnifibre Black Code 1.24 is a relatively soft polyester based string with a pentagonal shape for added spin.

$29

Babolat RPM Blast. Co-polyester from Babolat that is softer than their earlier offerings and octagonally shaped for more spin. Personally, I found this to be on the stiff side, but this is the string of choice for Nadal, Warwrinka, Fognini and others on the tour. Available in 15L,16, 17 and 18 ga.

$32

Tecnifibre Razor Code is the stiffest of the co-polys in the Tecnifibre line. Available in 17 gauge for the spin oriented advanced player.
