Strung my Bandit OS with my standard all Sheep Micro 17 job. Broke after 10 sets. First time I've broken a string in years. Guess my new topspin groundies are working. Had some extra Polyon 17 lying around so strung the Bandit with the Polyon in the mains at 63 and Sheep Micro 17 crosses at 61. Was really "hot" at first but settled down and is making for a great control combination. Can really place both volleys and groundies with spin and precision. I used this same hybrid in a Hornet MP and hated it, so just goes to show its the frame and the string combination that has to work, not just one or the other.
