I am a new to bike frame building but I'm an experienced welder and have done a lot of thin tubing work (headers, intercooler piping), so I don't anticipate too much difficulty welding it up.
As far as stiffness in the bottom bracket area, I have seen a few people putting gussets on their frames at the bottom bracket area. I do this on race car stuff frequently; any reason not to consider it here?
The stiffness of the metal is not effected by heat treatment, only the shape factor. Given this, Zero tubing is MORE flexable than the others because it's thinner. Zero is so thin you are not going to be able to do much cold setting to straighten the frame after welding so make sure you keep it straight during the build.
