I was warned about this so I read up on it, found out about line balancing, decided that was a right faff and bought a proper adjustable flow tap.
Its a bit of a faf when setting up, and involves 2 more jg fittings (2 x 3/8" to 3/16" adaptors) and a length of upto about 2m of 3.16" mircobore line.
Not all flow control taps are equal, and most are fine at lower pressures - upto 6-8psi in the keg (Mine @ 8psi(by my reg) and higher are impossible to set at the sweet spot requiering a fiddle every pint) but @6psi and lower (ideal for bittres and ales with a low to medium level of condition) they are a dream,, For the more lively pints lagers and in my case more often than not a ginger beer served @ upto 15psi i use the simple microbore solution for serving.
the goal is a nominal 1-2psi pressure difference at the tap/release point as a higher difference can stimulate a foam out..
I manage most of the year without any active chilling as my kegs sit in a well shaded out house that abuts onto the back of the kitchen, But come summer i need a shelf chiller to pipe the beer through as otherwise its foam city..
And i need to adjust the serving pressure and vent before most sessions to accommodate changes in the weather, and mid winter EVERYTHING IS FIZZY, and by the end of spring its tricky to contain highly conditioned brews..
A brewfridge if you have the room is a godsend, unfortunately they have yet to make one 34cm wide
So depending on the style of beer your after pouring you may want to look into investing in a short length of microbore..
The reason its a bit of a faf is that the metrics are all a bit fluffy, at the low pressures we are talking about reading regulators with gauges intended for larger pressures can be a bit of a challenge, but iirc the metrics are that the microbore line will reduce pressure by one to two psi per foot length, closer to one ps1 to start with growing exponentially or logarithmically with each further foot till about 20feet when its closer to 2 psi restriction per foot length.
So if your pour is just too slow with your first best guess at how many feet to use,
you just need to decouple the keg open the tap to release the pressure and lob off a bit more length..
Also be mindful to use a sharp blade and cut beerline square, dont be tempted to use scissors or shears as they will deform before cutting and the resulting cut can create neucleation points when inserted in jg fittings to stimulate a foam out in the beer line before the tap point is reached.
