i think all of them have their advantages from year to year. I shoot the switchback xt and love it. I have a buddy who shoots the reezen and he cant part with that. My father just bought a used z7 for $500 from bowsite this summer and he loves that so it is hard to tell you which one is the best lol. If you are buying over the internet i guess the only thing you can do is look into the specs of all the different models and find what meets your needs. Hope you find a good deal.
