The Zebra and Barracuda strings really are two very different critters. The Zebra's were terrible. The Barracuda's I've seen on the 06+ bows have been pretty good strings. The center serving isn't exactly the material I like but they are stable and don't creep any more than anything else I've seen.

With that said, Gibblet's strings are less money, and have better quality servings than anything I've seen yet.
