The JOOLA Infinity Series Overdrive Racket's carbon-Para-aramid synthetic fiber blade is a combination of 5-plywood and 2-ply Carbon-Para-aramid synthetic fiber to make a 6.1mm thick 7-ply blade. The wood is a combination of Hinoki, Koto, Ayous woods, and Carbon. Hinoki, viewed as the 'golden wood' of blades, is a delicate and dynamic wood fit for all styles of gameplay. Native to central Japan, it is used as the outer-plies of composite blades because it creates more control and increased feedback. It undergoes a meticulous preparation process where trees reaching 300+ years of age are hand-selected and then cured for 1-3 years before manufacturing. Koto wood has a diffuse-porous end grain, which makes the wood nimble and stiffer allowing the player to produce faster blocks and rapid counters. Ayous wood is lightweight, firm, and elastic which is why it is the heart of many all-around blades. Ayous is quintessential for players that want to keep the ball in play to wear out their opponents. Carbon-Para-aramid synthetic fiber is forged from carbon atoms that are formed into fibers about 5-10 mm in diameter. The 2-ply of carbon reinforces the blade and reduces vibrations while enlarging the 'sweet spot,' for a stronger attack. With the use of Hinoki as the outer ply, Koto as an inner-ply, and Ayous as the core, the racket gives phenomenal feedback while the Carbon-Para-aramid synthetic fiber, as the innermost-ply, provides uncontested dominating top-spin. Bullet-proof your game with the para-aramid synthetic fiber racket.
