Familiarity: I've used it several times
I have a set of these on a spare set of wheels for my cross country bike. They perform well in dry conditions. I had a not so good experience after riding through a stream on a local trail. When pedaling out of the stream onto slick rocky surface there was absolutely no traction at all. The rear wheel simply spun and the front washed out. Definitely for complete dry conditions or tacky dirt. From my experince, these will not perform well in any slick conditions.
