pv did not try the os/4s hybrid. He is basing his review on diff. ltec string. Does not feel like venom at all. I am not saying it is as great as some, but better than most polys I've tried, but it has to fit your style/frame and tension. Maybe he did not match those up is possible. He also stood up for performaxx, when the guy broke his word to me, and went awol for a bunch of us. It's not just poly, but ribbon injected poly like iso speed ribbon. It does last longer for that reason.
