I was having the same debate over which one to buy. I got the q2 and love it. I shoot a gold tip xt55/75, 125gr muzzy over a nap 3000. shooting 60lbs with a 30 inch draw i get 265fps. i don't know about the muzzy ze rest. its seems to be snowing a lot when i hunt and i thought that it might cause problems with the rest. hope this helps.
