What players say

Liked 2 sources

Tennis Warehouse playtesters and customer reviewers agree this pentagonal co-poly delivers strong spin and control from its five sharp edges, with tension maintenance that beats most polys. It plays firm and moderate-to-low on power, which some arms and swing styles dislike, and durability reports are mixed.

Best for

  • Full-swing baseliners who want extra bite and spin
  • Players who already string low and want more comfort than a standard firm poly
  • Hybrid setups, often paired with a softer or more powerful cross

Pros

  • five-sided shape gives strong ball bite and spin, called out by nearly every reviewer
  • good control from the predictable, lower-power response
  • holds tension and playability longer than many polyesters
  • comfortable for a firm co-poly, with several players calling it arm-friendly

Cons

  • moderate to low power; some reviewers say it needs a full, seasoned swing to get pace
  • feels firm/stiff to players used to softer co-polys, and a few call it hard on the arm
  • a few customers report it loses tension fairly quickly unless pre-stretched
  • durability was inconsistent across testers, good for some, not great for others

Voices

The five sharp edges really gave this string great ball bite and spin potential.

— Andy, Tennis Warehouse playtester, Web

The great access to spin combined with the stiffer, lower powered response equaled excellent control.

— Jason, Tennis Warehouse playtester, Web

Durability wasn't the greatest, and it played just a bit too firm for me.

— Jason, Tennis Warehouse playtester, Web

Awesome string, easy on the arm, great spin.

— Insang, Tennis Warehouse customer review, Web

Not much power though so make sure you have seasoned arms that can provide your swing with enough power.

— Matt, Tennis Warehouse customer review, Web

This is one poly where you should consider pre-streching -- it will hold it's tension longer.
