This thread is now 1156 posts long - 116 pages on standard settings - and I'm not sure it's practical for anyone wanting to catch up on the discussion (even with links in the initial post).
I'm thinking of doing a new version, pared down to only the most serious candidates, which at this point I would consider to be the following.
I'm open to suggestions on whether that pool needs to be expanded (though I really don't think so) or shortened. And if so, who do I add or remove?
Do it and I will replace this one with the new one.
