So far they've been great, though they seem to be a slight bit less smooth on the road than when they were brand new (though they're still no worse than my BFGs were). I've probably got around 1500 miles on them so far.
No complaints yet offroad, much less tread chunking than on my BFGs.
You get no choice with the white lettering on the sidewall though, either you get letters, or you don't, based on what size tires you buy (and turning them inward isn't recommended because of the asymmetric tread).
