This size is really good. I use them time to time. You have to prime them a little less sugar. Maybe half the amount. Too much priming sugar causes heavy foam problems. I can dispense one keg per one CO2 canister.
There are drawback as well. Cleaning them is PITA. You have to dry them completely...
Great recipe collection. My problem is that most of the recipes are in imperial units. I'm better and better in imperial units, but I still have to convert some of them. Is there an easy way to convert all the unit for me? For example I could not used to Farenheit and some of the various mass units.
