Confidential in short
Solinco Confidential officially launched in 2020 after being available privately for around three years to select touring pros. The pentagonal shape provides excellent spin - comparable to Tour Bite or ALU Power Rough. What sets Confidential apart is its exceptional tension maintenance, even at lower tensions. Stiffness sits between Tour Bite (stiffer) and Hyper-G (softer). The first hour can feel stiff and board-like, but after breaking in, the string settles into a very playable feel with outstanding consistency.
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.
