Interestingly, I have gone to pouring off keg into small pitchers and filling my 10 oz. nonics (my typical serving size glass - I gave up on shaker size long ago) from the pitcher. If someone pulls a small glass like the 10 oz nonic straight from the tap, it is a waiting game to get to the beer...and that is at 10-12 psi. A larger glass works a bit better, but pouring from the pitcher gives a quicker "nicely headed" glass of beer.
