no I haven't tried them,
BUT
I was gonna get some of the chrome ones off fleabay that fit a honda,
Then decided I could probablly make some off a old bug shield from a truck or car.
They'd already have a bend to deflect the air around you, they'd be as long as you want or need for winter riding.
you could rotozip or dremil them to about any shape you wanted and even cut out for your turn signals.
Just a thought.
One bug shield should yield about two sets.
Idea, good, bad, thoughts.....
