Goodness, is this thread not dead yet?
I asked this question so I could prepare a seminar a year ago; and ended up using bflat since no-one objected.
You'll find the seminar here: viewtopic.php?f=186&t=34707
(it may take a while to load as there are lots of images.)
So from that point of view, this thread has done its job!
But if there's a wish to carry on discussing tunings...
