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.
Poly Tour Strike in short

Stretched under controlled temperatures during production with high molecular weight for above-average tension maintenance and durability. "It definitely played like a control string" with power level similar to Solinco Hyper-G. Firm and controlled right off the stringer but not uncomfortable if you hit center. Above average spin for round polys - better than RPM Blast and Lynx Tour. Perfect for big-swinging baseline games like Shapovalov and Osaka.
