That doesn't look like the last Ultimate Sprag I installed, I think maybe someone was blowin' you smoke. The A&A Ultimate is a 16 element 6 bolt, not a 12 element like that one. It's a much better quality piece and would be much less susceptable to the roll over that you encounted. LBA, or the bolt in sprags still do not guarantee no failure but definitely help. That sprag looks like the old "striped out case" fix it, which used to be all that was availabe. Now the Coan Super sprag and the A&A 16 elements are superior to those old 12 elements.
