No experience with them, but I like the looks of them. 3 ounces heavier than Pronghorns, USA made, and only another $10 higher.
I had some old Pronghorns that were awesome, just wore the toes through I wore them so much (and didn't condition the leather, use Obenauf's by the way on all your boots). Then replaced with the new style Pronghorn. They're not bad, but the foot to me is a lot stiffer, less comfortable than the originals.
Have a pair of USA made Danners, (discontinued, forget the model) and I really like them a lot. In a hotel in Portland right now, if I had time in the morning I'd run by their factory for a tour. Maybe next month.
