I agree, as domains well all own generally can't afford to be lost, domain redemption is the only 100% way you can get it back without losing it. If you're lucky a back-order will work if no one else tries to get it, but if a website has a lot of traffic or a good name, it's probably gonna get snatched from you and not worth the risk. I personally have domain auto-renewal enabled to make sure that I don't end up in this situation again also.
