I was considering an integrated stem/handle bar with an 9 degree sweep back and 8 degree rise.  Does anyone have experience with these.  I am a big guy at 6'2" 225.  I would love to try one.  I ride cross country and trails with little jumps and stumps.  It looks awesome but I can understand that they can be brittle and snap.  Would being integrated help strengthen it?  What reputable companies make these so as to compare them?   thanks
