I use a trophy taker SHAKEY HUNTER. It is a drop away rest. It also is contored so the arrow doesnt came out easy. Now they also have a line that is full containment also!! I will post a pic of myne. They reduce almost all of the torque you can put on your bow when shooting, thus tightening your groups. Ase soon as you hit the release there is nothing coming into contact with your arrow.
Here is the one on my bow
Here is the one on the website
Here is one that offers containment.
What ever you go with , I beleive the dro away is the way to go!! Good luck, I hope this helps.
