I'm looking at trading off my SBXT for one of these bow but can't make up my mind. I have shoot all but the E500, I like the feel of both and love the speed. I don't really know that much about the E500, I have heard it is just like the Synergy but came out a year before. I think the Elites are alittle more dead in hand and quiter, speed are about the same. Thanks for any oppions.
