Got a lot to report tonight, but to start...
@David McCarroll - That V is from a kit? Looks awesome!
OK, received the Throbaks today. While I haven't had time to install them yet, and may not until next week (family coming tomorrow, then leaving for a short trip), I do have some initial observations.
First, here's the wiring kit. Looks very well done, including pre-tinning the backs of the pots to make that connection easier. As
@lscottk mentioned, it doesn't take a lot of effort, but it definitely adds to the end-user experience and I'm glad they did. Saved me a step or two.

I pulled out of couple of the other pickups I have around to try, including a BKP Stormy Monday, a Gibson Custombucker, and the Throbak DT-102. Here's a picture of the covers side-by-side...

Anybody want to guess which is which??
The top seems to have slightly more rounded corners, but it is much less obvious in person. I was actually surprised how much they looked alike. The bottom has a significantly shape, more so than I thought it would. So I checked this one against an older one I have, and guess what... I think BKP has changed the shape of the corners of their covers. BTW, the middle is the Throbak and the top is the Gibson.
So, while the shape may have a small effect on the resulting sound, the next thing I noticed was the difference in the thickness of the material used for the covers. I didn't get out my calipers (I may later), but the Throbak material looks to be about a third thinner. I don't know how much, but I can see this affecting the magnetic field shape, size, and strength and that could be an audible change. Of course, it wouldn't matter if I took the covers off, but...
Here's the Throbak (left) and the Gibson (right)...

Finally, and this is purely cosmetic, both Throbak and Gibson have the toolmarks on the baseplates. I have no idea which is more or less correct, and in this case, I don't really care. I do think it's cool that they included that detail.

A few other things I noticed... I ordered the BKP with short legs, so not fair to compare those. However, the BKP screw poles were noticeably shorter, maybe by 1/4" (didn't measure). And I know that's one way to affect the sound, it's part of some designs, and I've tried using different length screws before. I can only assume that this was done on purpose as part of the design BKP developed for this pickup, and it does sound really good, so no complaints.
I'm not going to take the covers off of these to compare further, although I'll take note of what I find when I fit the new magnets in the Custombuckers (I have 3 of them for this experiment).
Unfortunately, I'm running out of time tonight and I really wanted to hear these. Maybe not tonight, but tomorrow with any luck at all. I'll likely do the full run-through and capture some clips over the next week (maybe) or next weekend (more likely).
