While we're on the subject, if we're putting down 2 or 3 layers of water based satin poly, what would you recommend doing in between coats. I'm concerned that trying to do any screening or sanding could cut through previous coats and stain which would be a disaster.

How bad are the dips on the edges? It may not be as hard as you think but let find out why is it dipping. Tired or not enough foundation? If the first floor is dead flat, they never are, and I don't expect it to be on an old house, what is the cause of the our of lever second floor? maybe poor workmanship? Maybe the joists need to be shimmed where the dips are. I am not there and can't really see the house. It should not be a big deal, but the sub floor has to come out or access it from the bottom that's if the first floor is good. How many inches is it sagging? Leave it.
