We've had a chance to test these tires on the Mickelson and have deemed them close to perfect. They don't kick up gravel like the Ignitors did. They smooth out the ride almost like an extra set of shocks. I don't think I would be very confident with them on very rocky downhills, though. For trekking/off-road touring, they are amazing! I might even get a set in 26" for the old Gary Fisher.
