side by side mounting on a GEM

I find the observing flexibility of having two scopes available at all times far outweighs the couple of extra minutes I spend setting and balancing them. This assumes that I had a different setup in place the night before ... otherwise I just roll the mount/scopes out and observe (with no extra setup).
The only times I consider setting up two mounts are either when I've got a few folks over to observe with me or I might have a small alt az setup for a quick look at a planet or moon while the larger scopes are acclimatizing.

I have been just leaving the SbS bar in place and putting the imaging scope in one position and the guide scope in the other. Recently in an effort to simplify and reduce the overall weight of things when I'm imaging with the C11 I remove the SbS setup and put a small lightweight autoguider (based on a finder scope) underneath the scope on the Losmandy D plate. I've started to do the same thing with the 115mm refractor as well, but I haven't done much actual imaging with that setup yet.
I don't have any specific problems with the SbS when imaging other than the extra weight when using the C11 and the 80mm scope as an autoguider. When I go with the lighter weight setup I'm saving 12lbs or so (5lbs for the SbS, and the difference between the 80mm scope and rings and the 50mm scope and smaller rings).
