I have room for another corny in the fridge. I already have a tapper in the door and I don't really want to drill again. My question is this ... I have a tapper attachment that fits directly on the top of the corny without any intervening line. Will this work or will I have foamy beer. Seems like having 5-6' of beer line is important to avoid foam from the other keg. Anyone have one of these attachments?
