Great to hear your caught the GRS in the dob!

It sounds like you have fairly bad seeing in Ballarat... Under ideal conditions and scope fully cooled the dob should, at least theoretically, have a clear advantage over the small refractor.

Yesterday at 7:10pm I viewed Jupiter through my 8" F5. There was still day light and Jupiter appeared like a tiny yellow light in the sky. Even before achieving perfect focus the GRS was very obvious and showing colour. However the GRS was on the meridian making it easier to see. Jupiter was shimmering quite badly as I hadn't given the scope time to cool. A few hours later I was seeing much finer details, particularly in moments of excellent seeing.
