I switched from snaps to speed clips for crankbaits recently. I've found that they don't catch as much moss, but they're also a little harder to use. As far as straightening one out goes, there's no way that will happen on my crankbait rod. I would straighten a hook before I'd straighten a snap, and even then if your rod is limber and your drag is loosened a bit you'll be fine (knock on wood).
