The omen has a 5.5 inch brace height and the evo has a 6 inch. Idk if you guys have shot or just drawn any of the axe series bows, but my friend has the 2010 axe 7 and its draw is anything but smooth IMO. His is set to 31 inch draw aqnd 70lbs but he is also 6'6" and 270 pounds! If you are hunting big open country where you need to make long range shots, such as out west, then any of the axe bows would be a great choice (IMO) But if you are sitting in a stand up in the air, it becomes much more inconveniant to draw if you are at an uncomfortable angle. Its easy to get caught up in the speed game with all the new bows, but unless you shoot 3d or you need to make a 50 plus yard shot, Its unnecessary.IMO Also, if you are wearing heavy clothing like a thick coat, the 5.5-6 inch brace height is very easy to snag on your clothing or ping your are with! not fun when you miss because of something like that!
