...seems to me that you, Don, favored and older Guild F30. If you like that shorter scale perhaps you should stick with the Martin 000, as it is the only of the three you listed that is also short scale. They are also now making the F30 again (they had stopped for a while). I played one last year and my only complaint was volume. It also has a VERY un-wide (from E to E rather than neck thickness) neck.
