    This is the best string I have ever had on my head radical mp. You can apply as much top spin or slice from the technifibre black code as needed. It gives you some extra pop on your serve as well. I will never switch away from it to even try another string.

    Black code & luxilon are my two favorites... use in my 325... Tipsy endorsed this one last year and now I think Razor code... Although a little less bite than ALU Rough... it holds tension much longer. Love Tecnifibre
