Thanks for the compliment.
Yep, you are correct on the lug taper. Both have a similar +/- 60 degree acorn taper, but the smaller lugs do have a larger/wider seating surface. I torqued both types down, drove around a little and then rechecked them OK, and intend to do the same in a week or so. I wondered about that, too, but both seemed fine.
