More for show than comfort? If you say so.
I found them more comfortable than my stock buckhorns, more comfy than pullbacks, drag bars, and sit-up-and-beg vintage Honda bars.
I rode with 12" apes on my shadow for years, it never "ruined" my feel for the road, nor made slow speed turns dangerous or scary. They weren't shaky, they weren't flimsy, they didn't block my vision or make my arms tired or sore. They were comfortable, they felt right, they were perfect.
If you can only speculate, then state that your opinion is speculation. Don't pass off your opinion as experience, unless you have the experience.
