I'm not a shaker either, but then I'm a 135 pound weakling and can barely carry the keg to the kegertor, let alone shake it!
I do one of two things- set it at 30 psi for two days, then purge and set at 12 psi and drink in 4 days or so, or set it at 12 psi right away and drink it 10 days later.
I think shaking does work for fast carbing, but you'll have all the sediment stirred up and maybe have some foamy beer until it equalizes. I like just setting it and forgetting it- that works great.
Please don't double post! We see the threads.
