Not a huge amount of answers, but nice to have at least a few!
I've decided I don't like any of them enough - they just don't sound like the amph really does, so today I went ahead and re-recorded the entire shebang in an hour or so at the facility, and soon I'll import it to Cubase and see if it was improved. Changes included miking closer to the edge of the cone which really seems to have taken some of the buzz impact and made it much warmer, and also miking at 2 feet with an AKG414 in addition to far mike. And also used the Davette this time - it really is the best guitar I have and likely the best I'll ever have. Its strange combination of a strat type bolt-on construction but a gibson bridge with schaller rollers combined give it the stable punch of a gibson style axe but the thin rock maple neck and overall woods give it some strat type presence and immediacy, and it just makes for a guitar that is both superbly even and level sounding and very clear but powerful, much more so than the strats which basically only differ in bridge type and aren't tilt-necked.
It sounded much better there at least, but I'll see when I import the stuff to cubase.
And I will also have to try and recreate that sound in Amplitube as well...
