Draw yourself a plan, and avoid using tubing that is too large at all costs; half an inch in diameter can add a huge expense (3" vs 3.5", as an example). A big single, which I'm a fan of, not only saves weight and materials, but it can be just as power-efficient as the old-skool duals. What I've done is make the plan, then buy doubles of things like 45s, 90s, and straight sections from Summit. The mig will weld stainless just fine, if that's what you're after . . .
Universal = Universally necessary to cut, weld, and re-fit just as many times as you would with a completely random selection of tubing (or anything else universally assembled).
