I've got one on my razortec and love it. It did take some getting use to as has been said. As far as draw length, I shortened mine by 1/2" because I didn't like the feel of holding farther back on my release hand. I use the corner of my jaw as one of my anchor points and the added length of the loop kept me from hitting my wall because of the anchor point. After I shortened the draw length, it felt better and my groups came together very nicely.
