A firm, low-powered co-poly whose square edges bite hard and keep the launch low, so you need racquet-head speed to get depth. Its real strength is tension maintenance: it stays consistent through the 5 to 10 hour window where most shaped polys go flat, and the spin fades as the edges round off, usually before it breaks. Drop 2 to 4 lb from your multi tension (high 40s to low 50s is a common start). Suits 4.0+ baseliners with long, fast swings and healthy arms. If you want less board, try Hyper-G Soft; for a crisper, more precise response, ALU Power.
Best for: 4.0+ who want max bite. Feel: Firm, grabby. Gauge: 16L. Look at the gauge on the pack before it goes in the racket.
