I don't know about most people but to me, recently carbed beer just tastes horrible.
This is what I plan to do as well, I'm curious to find out how long it takes it to carb.This last keg I put 30psi on vented about 6x and stored about 2 weeks in the fridge under pressure w/o a line hooked up. Used my gas/beer line to serve my other keg. Once it was empty I hooked up the currently-chilling keg. Sunday it was flat, same with yesterday only slightly better.
