@parasailing I'd have to agree with @Chairman3 on this, Sapphire is an entirely different string than Hyper-G (either gauge). Both have their strengths, but Gamma Sapphire is lively, Hyper-G is firm and much lower powered. Sapphire is round and Hyper-G is strong shaped ( 4-sided) so it generate more spin, while Sapphire generates more power. I do think they could make a great hybrid though. I like them both, but they each bring something different to the game.
