I used em for a few days in utah 2 weeks ago. Im 6'5, 220 and rode the 193. I think they were mounted at recommended, which seemed fairly far back (but that might have just been my big foot). I really liked them. Super maneuverable if you wanted them to be, and held up at speed.
I just bought a pair. Chose them over my other options which were the atomic atlas, nordica helldorado, or the on3p billy goats.
