On a dare from a YTex FB colleague, I tried Hexagon Red, and while I was at it, strung Twisted Purple in my other racquet, Head Extreme MP, as the cross to the mains of Square X Sharp, 42 in mains, 40 in crosses. It beat Hexagon in durability, power, and control. And yes, beat the smooth polys, Protour, in performance. No doubt it has its market as a full bed, or even main, but consider it as a hybrid cross!
