Yeah I've seen my share of broken titanium bits, including a frame which snapped at the heat-tube. The main property that attracts me to it though is it's lack of fatigue-limit, which for a well-designed part can mean indefinite lifespan. Of course, aluminum parts are usually so overengineered as to eliminate the consideration of fatigue- limits from the equation, which is also why they can sometimes be heavier than titanium parts even though Al is a lighter material. I agree about the bolts being the most likely things to snap. For all I know, that's what happened to my buddy in his incident! Again I apologize for even bringing it up, it's, like, such a non-issue and only betrays some kind of neurosis on my part...
