I saw in passing a few years ago the contemporary Japan Bridgestone company had shown what was like a Hydro-formed steel frame
so increasing diameters and shapes to best cope with the stresses they had at those joints..
So, would be a bit more of a level playing field, for comparing with Aluminum structures of same shape, just different materials....
