Tenergy 64 (8.6) is the fastest Tenergy with effortless acceleration and spin-insensitive blocking design. Outstanding backhand rubber, light weight (around 48g cut), proven build. Modest short game and premium price are trade-offs.
Fastarc S-1 (7.9) delivers genuine tensor speed without excessive stiffness, typically under 43g uncut, making it lightweight. Excellent blocking and serve-return stability; grippy non-tacky topsheet with pleasing feedback; good medium-high throw angle. However, spin output noticeably lags Fastarc G-1 and top tensor rivals.
Tenergy 64 suits speed-first attackers and blockers. Fastarc S-1 suits intermediate to advanced all-round attackers seeking lightweight, forgiving speed.
