I have the Hondaline, and felt it made by bike shimmy at 77 mph. I have since switched to Memphis Shades, they are much bigger and are a much better design. No more shimmy at 77 mph. Occasionally, I do get a slight shimmy, but it is much better.
I'm happy with the MS lowers. I rode without them, and too much wind when up under the tsukayu BW.
