The ZR200' s are solid and dependable, just slightly lower in performance than the XT2000s. But the XT2000' s are a little more stable. It takes a pretty good tournament shooter to really tell much difference between them. If you shoot 3D seriously, then I' d say get the XT' s. If you' re just shooting 3D for funzies and want a solid hunting bow, then the ZR' s are likely as good as you need.
