Well, you can always just put in more arrows. I am a firm believer of never enough arrows.
Here is my setup.
I know, went to plastic but it works great. I noticed that when I was going through the thickets, even slow, when I swung it up under my arm, there was a noise. So, I just took out a small packet of tissues and pushed them down about an inch and that tightened everything up.
Oh yeh, while I was doing that, a hog ran in front of me about 15 yards up.
Maybe there is a note there about moving too fast.
