I have the flyscreen and the C-Bow racks along with the hard cases.
The flyscreen is effective and makes long stretches at 60+ mph quite doable. 60 mph without the screen was too much work for me. The screen takes most of the pressure off the torso, accomplishing what a flyscreen is supposed to do. With the clamshell ergonomics of the Bobber, it's a big improvement because you don't have a lean angle to counter the wind. Plus the aesthetics are very elegantly matched to the bike. I would attach it for the aesthetic alone. You will have more noise but not offensively so.
I don't have a picture of unadorned racks but I'll tell you it is very unobtrusive, believe me! (doing best Trump impersonation) C-Bow is the way to go on this bike, IMO, if you want to avoid the pregnant guppy look.
