the xt is actually a half inch shorter than the outback in axle to axle the brace height is about the same with the xt being 7 1/2 and the outback being 7 5/8 the major difference is the parallel limbs and longer riser on the xt and short riser and more upright limbs on the outback

personally i liked the outback better bc it seemed to shoot a little flatter but either one will be a great hunting bow you cant go wrong
