Jimmi:

My quiver is a bohning. It "suspends" the heads in the cover vs. securing them into foam. Ive never had a rage head open in the quiver OR from being bumped on stand.

I don't think I just got a good batch, either. I can't fathom why some people are having troublekeeping their NEW (not shot once or twice....maybe at a practice target????) rage heads closed.
