These two rubbers sit at opposite ends of the price and performance scale. Tenergy 64 is the fastest of the Tenergy line, with effortless acceleration on loops, drives and smashes, plus a spin-insensitive feel that makes blocking and countering easy. It shines as a backhand rubber and for speed-first attackers, but it carries a premium price and an unforgiving passive serve receive.

Loki RXTON 1 takes the opposite path. At roughly 15 dollars a sheet it offers very high control, usable spin and a light, easy feel that beginners love. The trade-off is low outright speed and only mild tackiness that wears off over time.

Pick Tenergy 64 if you are an intermediate-to-advanced attacker chasing speed and reliable blocks. Pick RXTON 1 if you are a beginner or value-focused club player building a first custom racket who prizes control and placement and wants a rubber cheap enough to swap monthly.

Which is faster?
