That one that I posted before fits both posts for counter filling plastic bottles with beer.
My method for maximum fizz at the moment is 30 psi 3/4 full soda bottle with brew of choice. gas it take off gas shake crap out of it till gas absorbs 10-20seconds then repeat this a few times and walla fizzy drink in less than a minute. I make sure it's as cold as possible too.turned out quite well, if a little under carbed. will definitely let the next one chill much longer before i hit it with the gas. i think the blackberry / lime would go quite nice with some brandy or rum
now to try that fizzy chocolate milk idea...
