Hyperion in short
Signum Pro Hyperion is part of the Blackline power series, featuring an optimized molecular structure for incredible power and touch rarely found in co-polyesters. The greater elasticity of the co-polyester structure provides enhanced comfort and power while maintaining directional control for hard hitters. Signum Pro suggests stringing 10% lower than normal due to the exceptional tension maintenance characteristics.
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.
