Jon,
I'm usually high on final and use belly board plus both rudders all the way to the numbers to get down. Could have better technique I suppose but would rather make the runway than come up short. Just the way I was trained. I like slipping but it has never felt right in the EZ.
Randy,
Jim Price set an altitude record using VGs on both canard and main wing. He developed the right installation, I believe, in a wind tunnel with a college project backing the research. They allowed him to fly very slow which happens at the upper end of the service ceiling. No Holiday Inn necessary, you nailed it!
