Maybe the height of glides (or jumps) should be proportional to the depth of snow.
Ralph, that is excellent advice!
I discovered what was wrong with my bar after e-mailing back and forth with the designer. The bar ends are supposed to be riveted in place. On my bar that step was omitted. It is clearly a manufacturing error as I checked another FS bar and sure enough there were the rivets. Clearly, FS has a QA problem that needs to be addressed ASAP.
