When it comes to polys, I like ‘em old-school!
One of the perks of being an avid tennis player working at TW is getting to test all of the new products. We test many, many strings (some that never make it to market and others we test from prototype through to production), but my love for traditional-feeling poly strings has yet to be diminished.
Modern co-poly strings blend additives to the polyester to ‘improve’ performance. Various additives are used to make the string play softer, hold tension better and provide improved snap back etc. These additives are the ‘co’ part of the co-poly name. However, I prefer to nix the ‘co’ and let my poly fly solo.
