During the research before building my Kegerator I came across a few articles which suggested that flow control at the tap is not as useful as flow control at the Keg Liquid Disconnect. Apparently gas is already knocked out of solution by the time it gets to the tap so flow control there is of limited use? Not saying it’s correct, just that the opinion exists. There are a few available, including a really nice Keg Kingdom Stainless Steel version which is very shiny and brings out the Magpie in me! I resisted and went with line length instead.
