753 is heat-treated a pain to work with.
I used to be a brazer at a cycle manufacturer for a year or so. There were two guys who were accredited by Reynolds (they were just down the road from us) to work with 753 but they still had a huge failure rate due to the steel cracking whilst cooling.
My preferred steel tubing is Columbus Nivacrom. About as strong as 753 but a LOT easier to work with.
Before they introduced oversized headsets Cannondale bikes had a racing lifespan of <6 months before failure. Can't imagine it is much fun coming down a mountain only to have your headtube separating itself from the frame halfway down!
Those guys at Litespeed are quite good. One of the very few welded frames where when I looked at them I didn't think 'I could do better than that!'.
Shame that titanium will never get any cheaper despite being one of the most abundant metals around. Most titanium is used in the form of TiO2 to produce white pigment but turning TiO2 back into Ti is rather difficult and thus expensive.
