M73, all good advice from the other guys, and yes, the double overhand stopper knot is pretty standard on many bridges, tree tethers, and lineman ropes. A short bridge makes it easier to maneuver the bow over, and if you are climbing with rope techniques like SRT or DRT, make it easier to climb. Some guys even install a two-bridge system, one for climbing on with the ropes and the other to hunt from when they are set at hunting height. If you don't want to cut the rope, you can always daisy chain the excess to make it more manageable. I hope this helps and that you have a great season hunting from your saddle!
