maybe the carbonation needs to even out? freshly forced carbed beers also seem slightly rough to me.

Force carbed beer should not be rough unless you do the super-high pressure & roll-the-keg method. Those who do the 10-12 psi for a week should have instantly smooth beer and the 25psi for 48 hour method is the same.
I do 30 PSI for a couple of days. it def smooths out after a couple of weeks.

Cant say I have ever seen this behavior before. I have seen the character of the head change... as in frothiness/stickiness but the retention generally seems the same from fresh to aged.
same

Okay, that's fine but "rough" should not be part of the equation. The character of the beer may smooth out over time but I consider it to be "good, fresh beer" right after carbing....it def smooths out after a couple of weeks.

Is this "crazy head" or just lively faucets & excessing foaming? THIS is interesting because there are times when a very light (almost gone) keg will fill on a super-foamy tap. But Chils said it happens with bottled beer too so...I find increased foaming/head after 3+ weeks in the keg - to the point of annoying when filling a pint.

over carbing?

It seems lately that all 3 kegs get the foam via picnic's. I typically shut off my lines when I know the beer is carbed. I even change out my lines quite frequently (7') just to ensure there's no spooge or other crap causing this. My psi for all 3 is set just above 10. It's getting annoying to fill a pint and have half full of foam.

Most of the brewing texts agree that head retention is caused by residual proteins in the beer. As a beer lagers some of these precipitate to the bottom. So in theory the head retention should decrease with age. What I don't understand is how a freshly carbed beer lacks head and has poor retention. My latest Vienna was as headless as cider for several weeks after being carbed. Its fine now with long lasting head. This follows suit with every beer I've kegged or bottled. What gives?
I would think it's becasue the CO2 hasn't had as much time to go onto solution as an older beer. That means it leaves the beer more readily.

Dumb questions coming up, but I'll ask anyway: Have you checked said keg's dip tubes for any obstructions?
For a 7' line, 10-ish psi doesn't sound terribly high to cause foaming from being overcarbed; if anything, perhaps the CO2 is breaking out of solution due to the serving pressure being too low? Just a guess.

Here's some general info in beer foam that may (or may not) be relevant....https://byo.com/stor...foam-techniques

I've maintained the same set up for a few years not but it only seems like the problem has been around for the past 6 months or so... I do check my dip tubes with each cleaning. I can see your point about the low pressure but again, my routine is not really changed. Hmmmmmmmm.

The only thing I can think of that makes sense to me, given what you've described about your serving setup, is an obstruction somewhere b/w keg and glass:
- poppets
- picnic taps
- dip tube
- serving lines
- quick disconnects
