I was told by VO that you could use the C925 on the SXW (25lbs max). I certainly believe that for visual but not completely sure for imaging. That was my reason for the SXD purchase so I could image with the SXD which runs about 33-35 lbs.
I agree, in my experience with my SXW, I would think a 9.25 would be FINE for visual. No way for AP (mostly because you'd have to add more stuff to do AP - guidescope, heavy camera(s), guide rings - all of which would take the weight way over 25#). I had NO issues with about a 23-24 pound load (4" refractor and 66mm guidescope, rings, plates, cameras, etc.) - so more of a moment arm than a C9.25 would place... and that was for AP uses...

Funny thing Bowerman, I went the opposite direction from CGE to SXD/Atlas. I won't be using anything bigger than a 10" SCT so that was an easy decision for me. Set up and take down of the CGE night after night got really old so I sold it for something smaller. Would have been good for a permanent setup but just was not in the cards this time.
The polar adjustments on my CGE sample were not very good and I do know there are mods instructions out there but it was the weight of the mount that did me in. Maybe again, someday, with a permanent location, that could change.
Sounds like the right call for your uses; in my case, I'm pier mounted, permanent polar with drift align, etc... So, no matter how hard/fiddly, I eventually get there and then just stay there! And I wanted/needed the capacity (eventually want a C11 tandem mounted with 80mm Triplet).

The SXD is noisy regardless of the load. Sounds the same even when there is no scope on it at all. That was the story for my sample anyway.

Unfortunate that it's noisy, but probably a function of slightly stronger (different) motors, maybe?
Amy, if you've played all around with backlash, I would seriously consider having it "tuned up" by the VO folks; it really shouldn't be Jerky at all.
