Yeah I am running two as well. Though I am running one under the lever mount to move the mirror around the wind screen.
You can see it here. The one that is mounted below the lever instead of above moves it out maybe as much as 3cm. Then there is another 3 cm riser. Riser seem to be of varying quality but this last setup and survived maybe 700 miles. Though the LWing has a very altered look it is highly functional.

The fender business is ridicules. Though it does seem most people are nice weather riders. So perhaps a valid design choice. I wish the front handled the rain at slow speed a bit better. Don't really love the water in the face thing it does below 20.
