I don't know if any of you have tried force carbing? My HBS gave me some pressure bungs that he had left over. (They had a vent in the center piece that supposedly released excess pressure.) I used one and it released all pressure, not just excess. So I had a cold keg and I tried force carbing by adding pressure and swirling around several times over the course of two days.
My beers taste a tad flat but they are pouring with a very nice head that stays nicely on the beer. I won't try force carbing as a rule but in a pinch it is working out.
