I am actually going through the same comparision as you, I don't want to change my mount (G-11 with Gemini) so those same scopes are coming up for me. I mainly use the Tak FS-102 refractor at the moment for photographic work but want a larger scope for both visual and photo's, this will be coupled to an SBig ST4000XCM and AO-8 in the new year.
The Mewlon has the lead in my book at the moment.
Cheers
