Checking the Columbus website, the only tubesets they list with the unbutted sections of maintubes thicker than 0.5mm are Thron, Aelle and Gara, the latter two being straight gauge. The website doesn't even list SL, SLX, EL, or EL-OS. Looks like the options are very limited for building a frame from Columbus if durability is a high priority.
