Mostly the material characteristics, my day job is as a material scientist so I have a pretty good understanding of this. I am not a professional welder, if you follow my build thread you would see I only began welding about 6 months before starting the project, all self taught, reading, youtube tutorials etc. Chromoly weighs the same as mild steel but it is stronger so you can use smaller tube, thinner wall to save weight. The downside is you must weld it following strict guidelines, your welding technique must be on point or you can end up with brittle welds. Mild steel is much more forgiving to weld so I see less risk in using it and I take the weight penalty.
