I am considering going to a drop away rest. I think that I have it narrowed down to the GKF TKO or the MBG Trap Door. I have heard good things about both and I found them both at a local shop for about the same price. The TKO was $43 and the Trap Door was marked down to $48. I am guessing the Trap Door is last years model and they are moving them out for the new ones. Any advice or experience with either rest would be helpful. It will be used primarily for hunting and a little 3-D shooting.
