Which caliper you use? There are 3 wheeltop models..thanks
The latest TX calipers - not sure what they are officially called. But the new ones.
I moved the TX groupset to my Gravel bike, figured I would try it there before selling it, as I suspect I'll take a beating if I do sell it

. But, tbh it seems to be working better with 11sp (Shimano). Had to really max out the FD setup to deal with the GRX wider chainline, but it does reach. Re the issues on the 12sp Domani - my
guess is that 12/13sp might be a bit problematic for the TX, while the (relatively) more straightforward 10/11sp setups it does better with. But just a guess. Might be some operator error in there as well lol, although I worked on it quite a bit (several weeks) before deciding to pull it.
Also, when I pulled the brakes this time there was no mineral oil on the backs of the pads, so maybe it was just a "getting the pistons seated" kinda deal... first time there was quite a bit (as pictured in my OP), 2nd time I pulled the pads to check there was still a bit, but less than the first time, and this time there was none.
I will say, one complaint I still have is the shorter chain requirement of the WT setups in general (due to smaller derailleur cogs based on comment earlier in the thread) - you basically "ruin" a chain because you've shortened it past what most other group/brand setups would need. So my advice to anyone "on the fence" would be to start with a lower cost chain, that way if you decide you don't like it and move to something else, you won't have effed up your DA chain

. For my swap to the 11sp gravel, I put a couple links back in it since moving from 11-30 to 11-34 cassette, and didn't want to cut another chain lol. I know that's not the norm anymore, but before quick links we all used to re-pin chains, so it will do for testing, anyway.
