After searching though numerous feedback posts on Puig, Dart Flyscreen Original, and Dart Marlin screens, it would appear that whether mounted to any of the CB1100s regardless of year, because of the rubber mounting system the headlight brackets are attached to, there is going to be some shake. Kudos to SportsterDoc for identifying the source of the shake associated with headlight bracket screen mounting systems. Smaller screens like the Dart Original Flyscreen, I think will likely have shake, but less evident that larger screens. It would also appear that the only way, as a result to drastically reduce or eliminate shake, is with a screen supported by handlebar stays. Of all the numerous reviews read, the Dart Original, and Marlin appear to have the most favorable comments.
As I posted at the beginning of the thread, I had originally thought about the Road Comet, but that it was a bit more than what I wanted. I like the look of the RC, so the Dart Marlin appealed to me as being somewhat similar in size and shape. What I did not know was that apparently RC owners had experienced shake with it ( and we now know where that shake probably comes from ), until I found and read this post:

With so many positive comments about the Dart Original and Marlin, size, shape, look, and bike specific brackets, I will probably go with one of them and am leaning toward the Marlin at the moment. I pity CB1100 owners that do not have access to the wealth of information the Forum provides.
