Hi Carl, with that setup, the scope mounting is not going to be a significant source of flexure. The places you want to pay attention to are the focuser and the camera attachment as both of these can move slightly as the scope moves when tracking an object. If you are guiding, then any relative movement of the imaging scope and guide scope can give you problems as well.

At your focal length which is less than a metre, it will be reasonably forgiving. Have you taken any images with this setup yet which you think might show some flexure happening? The rule here is if it ain't broke don't fix it. Worry about flexure if you are getting it, but if you are getting good images, then don't spend money chasing problems that might not exist.
