How often should I reraise the river with a monster, but not the nuts?

I agree with you that, if BB was a good player, the only hand that makes sense, once he 5-bets, is 55. But a these low limits I've seen the strangest plays. At higher limits, maybe you should call after a 5-bet, like you propose. At this limit I think I should have 8-betted or maybe even 10-betted. (not being sarcastic)
