The force carbing sounds like a good idea, except my keg kind of broke, and as a result it's still air tight, but I no longer have anywhere to put a CO2 bulb in. Also, I'm guessing I wouldn't have the equipment to set the psi.
So looks like priming sugar for me. I don't want it too carbonated, but obviously don't want it to be flat, so I guess I'll do 3/4 of a cup. Thanks.
