Any other suggestions?
longer will always foam less. but your flow rate will decrease given a constant pressure. Line diameter is more important than length. smaller is better for flow control, but same rules apply, small diameter, slower flow.
The last piece of advice, check the recommended serving pressure/temperature for the beer your getting. If you serve at a lower pressure or higher temperature than it is intended to be served at then you will have foaming problems that get worse as the night goes on. this is due to the CO2 leaving the carbed solution since you are holding a lower partial pressure than what the solution is at. you can always run higher pressure colder temps, and longer lines with small diameters and get beer that flows without foam, but that leads to over-carbed beer if you don't kill it that day.
