Neither had I. Things are changing rapidly in the mountain bike field and, to their credit, they are moving in a direction that they haven't gone in since Suntour came out with the Alpine AG stuff back in 1981. On the other hand, this is all very high end, very new technology. I find it best, given past experience with cutting edge mountain bike stuff, to let the new tech settle a bit before jumping on it. I wouldn't mind being a test pilot for new technology if I didn't have to use my own money to do it. It's easy to get burned.
