I use an EQ6 pro with EQMOD. On it is a VC200L and a 127mm APO refractor that doubles as a guidescope with a QHY5 guider.
The EQ6 copes very well with this combination. I'm sure that the G11 would also cope and may be better but it is vastly more expensive. I can achieve guiding well within 2 arcsecs over a 10 min exposure at 1800mm fl. Anything longer is limited by flexing between the scopes. Using the internal guider on my SBIG camera essentially gives me limitless exposure time.
Getting a more expensive mount would be nice but bang for buck the EQ6 copes well with my setup.
Note that the VC200L is much lighter than an 8" SCT so that option might be a different story.
