The High Modulus Polyester Compound ensures a firm feel and extreme durability, making it the top pick for performance players and heavy hitters. Thermocore technology brings flexibility despite the rigid material by using heating and cooling phases. Playtesters found excellent control (8/10), good feel (7/10), and surprising power for a 16 gauge co-poly. The Blue version is softer than White with a little more pop. Recommended for rackets over 300g.
Poly Tour Strike in short
Yonex Poly Tour Strike is a firm polyester for terrific control and tension retention. The name of the game is CONTROL. Stretched under controlled temperatures during production with high molecular weight for above-average tension maintenance and durability. "It definitely played like a control string" with power level similar to Solinco Hyper-G. Firm and controlled right off the stringer but not uncomfortable if you hit center. Above average spin for round polys - better than RPM Blast and Lynx Tour. Perfect for big-swinging baseline games like Shapovalov and Osaka.
