ETA: Been considering a Mathews Monster.
I have a Monster and its a beast. Real fast, pretty dang quite. It is torquey though. and it has a 7" brace height. I would hate to try the one with 6" brace height.
It is the first bow that, and I have had 6 or 7 speed demons, that I could set my first pin at 30 yards. 0 to 30 there is not 2" difference in point of impact.
