The Ardennes+ I had before let the 25s expand to a measured 28 and I was able to run them quite a bit softer. That was very confidence inspiring, but the wheels were appreciably heavier too. Maybe I'll drop the pressure in the GP5000s 5 psi and see if they behave a little less sketchy.

The first time I put light wheels on a bike, I think it stopped feeling novel after 6 or so rides. Maybe you're just more sensitive to it than I am.
I do remember the front end becoming a lot lighter.
I think the ones I put on were alloy and on the high side of 1500g,, coming from the stock DA-22 at around 2100g

These wheels make a noticeable positive difference in how the bike feels most of the time and maybe I am more attuned, but I have some trouble attributing the wobbles to that. They are the first carbon wheels I've ever tried.

Did you maybe square off the tires? I remember last year an issue where I squared mine off in long-straight tri training, then rode them at COTA and could feel a lot of squirreliness on curves as the tires flopped over the newly-sharp shoulders.

Common solutions, place a knee against the top tube. Lift butt off seat slightly, loosen death grip on bars. Move weight rearward. Have front wheel checked for improper spoke tension. One all or some can be employed.

The tires are new and we're not talking curves, just bumpy straights at speed. On smooth pavement, it's still a delight. The more I think about it, the more I'm convinced the main problem is me stiffening up because of how the bike feels.

Wind
Speaking of wind... just wrapped up my day and was going to go for a short ride but it’s blowing 25 steadily and gusting to 50. Going to have some gin instead.

Are you having speed wobble, or just a unfamiliar shakiness at higher than normal speed. Speed wobble sucks.
Common solutions, place a knee against the top tube. Lift butt off seat slightly, loosen death grip on bars. Move weight rearward. Have front wheel checked for improper spoke tension. One all or some can be employed.

Stepheeeeen!
I hope they stay ok.
My SIL, a firefighter, has to quarantine for 2 weeks, 3 members of his company tested positive. He was already home with my daughter and 4 month old grandson, to say my wife and I are worried, does not begin to describe the feelings.
Please everyone, be careful and keep the distance.

I switched from a Felt F5 to Z4 back in 2015 prior to having some surgical repair done on my hip. Despite what is supposed to be a more stable bike, it felt odd, and I always stiffen up on descents. There is one where 50ish on the F5 felt fine that I’m afraid to do faster than 38-40 now. I tense up and get speed wobble.

Incidentally, the bike is an R3 with discs and it should feel great on anything.

That sounds likely enough, given everything you're ruling out.
