FYI, Beer in a keg conditions much faster than in a bottle. If you can keep you hands off the tap that is.
7 days in keg, cold @ serving pressure will carbonate the beer as well as perform a cold crash to settle out floaties etc. It will therefore clear your beer and carbonate it. That is a win / win no?
Leave it another week on top of that and it is very good. Another two weeks and it is absolutely magnificent. You will pat yourself on the back, hi five imaginary people and proclaim that this keg thing is absolutely f*cking amazing. Then you will go to pour a celebratory beer from the keg to toast your awesomeness, but all you will get will be foam. Happens every, single time. It will leave you hollow, crushed and at a low point. Until that is, you swap the disconnects over to the pre-carbonated spare keg and the journey starts over.
At kegging time in a 23l batch you will need 6 stubbies for the last 2L so you will be able to keep them stored an conditioning as per current process.
Either way, glad to see you are enjoying the hobby mate. There is no right way, or wrong way to enjoy it.
Cheers,
