The cams on the Reezens do look pretty aggressive, which probably explains the speed increase, and of course the lower brace height on the 6.5 model. Can't wait to shoot the McPherson Monster. Probably won't buy one, but I do get a speed kick at the range. I'm with the above mentioned, I like a smooth draw for hunting. My DXT shoots 280 at 63 lbs, which is plenty for anything we have roaming around in our state.
