I'm trying the premium gut, which was the lower price. Mamba recommends it be strung at lower tensions. I strung it about 55 and was sweating it as I finished up. Finally got it strung, and it seemed to play okay. I've got it in the crosses with a poly main, but am not crazy about how it plays. I've become used to a muted low power feel, so the gut is too lively to suit my taste at this point.
