Vortex in short
Prince Vortex is a shaped co-poly with a hexagonal profile and softening agents in the material. In the Tennis Warehouse playtest its strongest score was spin, and TW notes it has one of the top spin scores in the TWU string lab. Comfort scored very high for a co-poly and power was lively for the type. The trade-off is tension: the TWU lab measured a high tension loss, and testers raised tension and pre-stretched to manage it. At about $8 a set it is one of the cheapest ways to try a spin poly.
Hyper-G in short
Since 2014, Hyper-G has endured as the top string choice for tennis players around the globe. Developed for an ATP top 50 player, this shaped co-poly with an impressive combination of spin and precision allows big hitters to take massive cuts at the ball without having to worry about overhitting. The square profile with sharp edges bites the ball at contact, generating massive spin. Topspin players who like hitting balls that dive sharply and explode off the court should love this string. With an unmatched selection of 7 gauges from 15L to 20, there's a Hyper-G for every playing style.
