Just re-read post. I don't entirely agree with your assessment of all non Columbus/Reynolds frames being junk. I'd take my Fuji's double-butted chrome moly frame (with no indication of manufacturer) over my Super Course's 531 main triangle any day. To say that the best Japanese tubing (and likewise the best Tange tubing) is inferior to Reynolds and Columbus tubing tells me you've never ridden them.
