TimI don't know your collecting tendancies, but given mine this is what I would do.
Leave the card slabbed for the time being. I wouldn't crack it until it was one of the last cards needed to complete the set. By that time you may come across a raw card at a good deal that fills your need and you can then sell off the slab. If for some reason you give up on this project it will make moving the card easier and you don't run the risk of resubmitting and receiving a lower grade.
