After lurking for years reading this forum, I'm jumping in real quick to plug the write-up I posted today on Fairfax. There isn't much new under the sun than what's already been said here (any one of you seems to know loads more than I do) but it may help you tie things together. Also, my working model is available for download at the bottom of the post. Feel free to change it around based on your own assumptions.
