I like the ditch brackets and would definitely get a set. The Yodateq mirror-mount style is nice but, for those of us that live in areas with lots of low-hanging branches and narrow trails, the side-mirror location is totally exposed to trail damage. The edge of the hood/ base of the windshield, on the other hand, is easily protected with a set of limb risers. I agree that getting them as low and outboard as possible would be good, but definitely inboard of the fenders for me.
Also, any progress on that factory CB antenna mount kit you keep teasing us with
