Serious tennis players, listen up! The TRU PRO Black Knight string is what happens when innovation meets performance. This 6-sided co-polyester blend gives you that perfect sweet spot between power, control, and spin access that tournament players dream about.
Here's the crazy part - it's actually arm-friendly despite being a high-performance poly. Based on USRSA lab results, this stuff holds tension incredibly well and offers outstanding durability. No more worrying about your strings going dead halfway through a tournament.
The gauge recommendations are spot on too. 16 gauge is perfect for advanced to pro level players (NTRP 5.0-7.0, UTR 9-16+), while the 17 and 18 gauge versions work great for intermediate to advanced players. Comes in black and available in sets (40ft) or full reels (656ft) for stringing pros.
You'd think with this much softness and playability it would be springy and lose tension fast, but nope - that's actually one of its strengths. Great directional control, exceptional durability, and enough spin access to make your shots really bite. If you're tired of sacrificing comfort for performance, this string might just be your holy grail.
