I'm not sure about doing the out of service then going back in on the qc thing to get one. I know if you've been sitting a while and call your cc they are not giving them at all anymore that way. The problem with doing the force on the qc is you run the risk of losing your spot on the board if you don't like what it gives you for a empty move.
only go out of service then back in if your on the bottom of the board or plan on moving or are moving anyway.
