Bit of an excavation for this thread, however for completeness I thought I'd update:
I've been able to borrow Rick's ST11K to try in my system. Unsuccessful, but informative. My focuser (moonlite) is too weak to hold it and my OAG causes vignetting. Doing a larger frame camera upgrade basically means buying everything from the camera to the back of the scope.
Unless I get some more information to change my mind, I think I'll hold off on any upgrades this year and reconsider my options next year - hopefully with an increased budget overall to expand those options.
