I always heard that with Ti, the welding is the key, and some of the welding on this frame - especially the previous repair - is quite sloppy looking. There are differing opinions as to the mystique of titanium welding - some maintaining that it’s super technically demanding, others saying that, at the end of the day, it’s just welding. Either way, there’s something to be said for going with manufacturers like Litespeed that churn out Ti. The frames may not be ”boutique”, but the builders have their act together. IIRC the Reilly Bikes mentioned in the linked article are one of the only, if not the only, firms that draws their own 6/4 Ti tubing, as opposed to rolling and welding sheets to form tubes.
