Re: So I swapped out the wheels and the creak went away.....

...what do I do now?

The lockring (Campy Chorus 10 13/29 cassette) is torqued to spec. I
removed, cleaned, greased and replaced the cassette. Checked that the
freehub nut was tight, removed it anyway, checked bearings in freehub,
turn as if nicely lubed. Lubed threads on freehub nut, re-installed
tight. Like buttah, no play. Hub axle also turns like buttah, no
play.

A while ago, I was sure it was the spokes so I applied my tensiometer
to the spokes but they were all well within 10% of the mean tension. I
took the opportunity to true the wheels (minor tweak) but that did
nothing. I also lubed the spoke sockets (CXP-33's) to no avail.

So I would go out and ride it to see if I took care of it, but it is
raining here. Managed to beat the rain this morning but no dice now.

If the above-recited attempts don't solve the creak, where would you
go next?

Cassette has minimal wear, as far as I can tell (but I did get it on
ebay). Loose rivets on the cogs with carriers? It was a cyclical
thing but lately it has been every pedal stroke mostly when standing.

QR, perhaps?

Help! it's driving me nuts!

So you've narrowed it down to the rear wheel? Sounds like it, but in
the subject line, you mention swapping both wheels. If you're sure
it's the rear, check the non-drive side spokes and the bearing
adjustment again for looseness. Don't worry about spoke tension
values, just make sure none of the spokes are loose enough that you can
wiggle them without much resistance. And you're checking the hub
adjustment while it's clamped in the dropouts, right?

It's not your cassette, since loose lockrings and worn cogs don't creak
(and the rivets do nothing). If you have some wacky hub, I guess it's
possible your freehub is creaking, but that's a rare one, too. Rear
wheel creak is almost caused by a loose spoke or loose bearings.
