Re: Question about standard sized pots and mini's..
I've done work on a Sheraton, I used dime sized pots and push/pulls. It's easier to get a dime sized pot through the f-hole, but then their smaller size probably makes them somewhat more difficult to maneuver once inside (more liable to flop around, not stand up straight, are further down from the mounting hole).
Regarding the quality of either, for me, their failure rate, or how often they need to be cleaned, has been equal. Here's a semi-entertaining, informative video about how awesome old Gibson pots are that, if nothing else, dissects pots.

IMO, most of the differences between various pots in general are immaterial to performance. They'll say one has a thick strip, but if you never wear out a thin strip, what does it matter? Even the expensive pots are open to air and liable to attract dust and whatever else. I don't know why closed, air tight pots aren't a thing with guitar electronics. It mostly comes down to whether you want easy spin, or resistance in the spin, and there are both quarter and dime sized pots with either characteristic. I think a lot people just assume bigger is better, or more expensive = better, that hasn't been my experience with guitar pots.
