Most full length arrows are 32" I thought, but the loop won't make any difference, and really if you adjust the draw-length to adding a loop, you could actually shorten the arrow. As long as the arrow has clearance, it shouldn't be a problem really unless you're shooting some of the wild turkey BH's that need greater clearance. If you'd like to gain more clearance, you could cut your DL 1/2 and use a little longer loop, and it will essentially give you a little more arrow past the rest, without having to buy arrows.
