I should clarify. I've always been a crank-and-shake guy, but parts of me are getting a bit old for shaking kegs. I've put a stone on a tube on the gas in, but discovered that it causes gas breakout in the keg when dispensing (by the end all your hop resins are in dried foam on the sides of the keg) hence my interest in having a third post. I'm just wondering if anyone has tried this particular product and has found out anything I need to know.
