20feet and 25 feet of 3/16th line (one is designed for beer, one is ice-maker poly line). Temps I run are around 40-42f, and I'm up around 11-12psi usually. Pours are great from both taps, but the 25foot poly line is pretty slow. Takes a good 20 seconds to fill a pint glass. The 20 foot line takes half that, but neither foam up at all now.
The flip to that is my 25 foot line makes a GREAT bottle-from-the-keg tap, without making any adjustments to pressure at all.
