My 2c:
I'd go 4130. Better strength to weight. TIG, braze, or O/A.
If you must use a lesser welding process then go with the 1020 CRS. If you plan to add bends then I'd choose DOM.

On the whole, I think you would be shocked by how much lighter and stronger the 4130 is. Worth the cost difference IMO.
