I was going for the greatest weight savings and strength. When I started the conceptual design cost was not a consideration; only weight and stiffness. Welded-up 4130 nodes would work fine - only drawback might be distortion during welding requiring some "truing-up" machine operation which would most likely cause the wall thickness to go undersize, weakening the node. If I remember correctly the compleated frame (DSR) would have weighed somewhere around 25 pounds.
