Lighter than 80-20...most definitely! Just about any chassis short of one fabricated from steel is lighter than an 80-20 chassis. Of course this is a bit of an exaggeration but 80-20 is a heavy material.

As for the tube chassis, I would think that a welded 1/16" aluminum tube chassis would probably be lighter as well as a bit easier to manufacture than a sheet metal frame.

Sheet metal is nice if you have the resources and if you understand how to design to its strengths, but I dont see it as the miracle construction method that a lot of people on CD seem to see it as.
