I used to not check them very often (and even shot one that had minor scrapes on them when I was new to bow shooting) but last year my brother in law picked one of my arrows up out of my case and had it blow up on him. Bent the hell out of his cams on his Allegiance and scared the crap out of both of us. (btw this was one that I didn't know had a crack in it). I don't check after every shot now, but I definitely check more often.
