What type of riding do you do? I'd be comfortable (sort of) with a big, shiny rock on a road ride, but I think I'd leave it at home on a MTB ride.

For me, at least, it all boils down to how active (for lack of a better word) my hands are going to be. I'd hate to knock the diamond off. Yeah, I know, insurance and all that, but still.
