I've been researching fairings for the Tour Easy, and it appears that they come in a range of sizes. The Zzipper web site shows 5 different versions for the Tour Easy. Some are wider, some are shorter. Some are designed for a bodysock (although I do not see anyone who sells a bodysock). Some are tinted, while some are clear. Any suggestions on how to choose one? Is it worth the extra weight to have a wider one capable of mounting a bodysock? (Or does anyone actually sell a bodysock?) Is tinting a concern for visibility? What about noise? I have read that fairings can be noisy. Any suggestions are appreciated.
