    Great Action
    This shopper rated the product 5 out of 5 stars

    Great control with these strings. I went to 18G so I dont get the elbow pain experienced with Heavier gauge strings. If you dont break strings often I highy recommend these strings for great feel and Power.

    Black Code in Name Alone
    This shopper rated the product 2 out of 5 stars

    I've always been a fan of the original Black Code. Knowing that this was intended to be a stiffer, lower-powered string I thought I'd give it a try. I strung it up 3 different times in full bed (both one and 2 piece) and a hybrid. Sadly, it doesn't maintain it's playability very long, turning increasingly more dead for me each time during 3 hitting sessions over 5 days. Eventually, it was basically spent. Had it not been for the Biphase crosses, I'd have probably cut them out for being practically worthless by round 3. But, if you like a low powered, dead feeling poly this might be for you after the initial break-in period. For me, though, I'm going to pass.

    Excellent bite and control. Using it for mains crossed with Solinco Pro Stacked in Wilson Pro Staff 97S.
