I'm not sure they even supply 753 any more - I believe the builder had to supply two sample 753 frames to be sent back to Reynolds and cut apart for them them to check that the build was of sufficiently high quality before they were certified to use it. It was very, very thin.
I know Rourke, for example, TIG weld their 953 (i.e., stainless) frames because there's much less heat damage to the tubing, but I also thought that certain tubing actually gets stronger due to the heat from the brazing process. 853, maybe? Not sure.
