Gosen has created one of the most arm-friendly co-polys on the market. Not only is this a great string for intermediates who want to transition into a control string, but it's also ideal for advanced players who want control without a lot of shock. This special blended polyester monofilament adds a twist. Literally. By twisting the string in the extrusion process, Gosen has given Sidewinder a textured shape for increased ball bite. This, in turn, enhances spin, allowing for better control. It also offers excellent durability.

This string received one of the lowest stiffness scores for a co-poly in our Tennis Warehouse University String Lab
