I think Pablos comments on the CF rentals getting abused is a pretty good endorsement that you can trust the CFs for DHing. dminor wouldn't post pictures of crap that couldn't be trusted. He seems to know a thing or two about the segment of Mountain Biking. Most manufacurers won't release frames for DHing if there are going to be law suits associated with breaks. Its a good time to make the CF jump. (oops, no pun intended)
