Trophy Taker!!!!!! I set them up and leave them alone. bullet proof and works like a charm for 3D or hunting. I can shoot just as good with broadheads from my hunting bow as I can with my competion setup. Trophy Taker are simple to setup and east to tune. One of the best features is 2 large screws is all that you use to adjust it. no tiny set screws to strip out or break....Try it, You will love it!!!! Bowjunkie
