Interesting stuff on the OSB Rocky. We are in the very early stages of home design research and many of the builders use OSB. After reading your info I'm definately going to insist on plywood. The shop we just had built has a plywood roof base, that was one of the real features that they played up, now I know why.
When I get ready to finalize designs I'm going to post them up here. All this input it great!
