Riding at Lucerne last week: Buddy launches his CR500 out from under him, it goes up 5 feet, lands on the back wheel, comes down on its side, and it bent the s**t out of his ProTapers. They didn't break, and the bike was rideable, but they were very bent from what I would call a fairly small crash. (For the record, last year, he cracked off his stock bars at Lucerne, so he is really hard on bars)
I have the ATV mids on mine right now. I am 6'1" and I needed the height. I like them so far.
