+1 I do pretty much the same thing. I have a short line with a picnic tap that my bottling wand fits in. I prime it in the keg, purge with CO2 and put a little pressure on it and bottle a 12 pack or so from there. Then just leave the keg to condition for a couple of weeks to carb up naturally and hook it up to serve.
