I'm not sure what kinds of targets you guys shoot at, but I can't remember when I've last broken an ACE from the point end. Impact breakages at the nock end, yes, but even shooting at wooden frames, I can usually get them out in one piece.
Maybe it's some specific spine ranges, as I generally shoot arrows from 370-430. I think I've used about 10 dozens in last 12ish years, and still have about four full working dozens and about 30 odd mixed arrows for blank baling left. Most (other than competition sets) are so worn that there's no labels left.
Always used the white hot melt with all arrows, apply properly and there's zero problems.
