Mmmmmm ... if you're trying to crawl through washouts on deconverted logging roads, like paragliders exploring for launches do, 70°+ approach angle is pretty damned handy. My custom welded up jobbie of a bumper on my old Trooper had an effective approach a good bit better than 70°, and it was not terribly unusual to need every bit of it and more. Beat the living crap out of the stock rear doing dumb stuff like that, of course, but hey.
