Admittedly I don't have a lot of experience although I have brewed and kegged 3 or 4 lagers since I began kegging. These were lagered in the FV for two weeks before being kegged and put straight in the kegerator and carbonated. So, stayed cold the whole time. They definitely were tasting better towards the end of the keg though, so I'd imagine you can do this and you'll get just as good a result if you can keep your hands off it...
Edit: I wish I had a third fridge for this kind of ****.. .would be nice since I can't not drink them once they're in the kegerator. :lol:
