How many of you that use them place an extra o-ring, or rubber band, over the blades to keep them closed while in your quiver? If you do this, what kind of bands do you use? I picked up a couple of packs in the hope of shooting a turkey with them this spring, but after taking my brother,my business partner, and a friend, I didn't have much time left for myself. I have shot them through a pc. of leather stretched over my broadhead target, just to see how they open, and they performed well. The only thing I am a little leary of is how easy they seem to open just carrying an arrow tipped with one. Any thoughts would be appreciated.
