Hey guys, thanks for the clarification - I resisted using Rom Loader /changer (whatever the heck it's called) since it cost 4 measly bucks, but then just gave up and used it to load the Google apps pack. Worked perfectly, and now I can change roms on whim.
So far I really like the default Blackdroid theme on Ultimate Droid, running at 600 because 1gz blew through battery life (though I think the battery notification was off).
Fast, stable, and slick - though I'm sure I'll try more roms soon.
I like cyon but I'm too lazy to track down kernels and all that jazz so ultimate was a nice quick fix (though I get that they stole code)
