We actually originally designed our drive base to use 80/20 or 1x1x1/16 box for versitillity in case we didn't have welding capabilty anymore. I'm all for that type of flexibility.

I however disagree with your comments on weight and strength. The shape of 80/20 gives it superior stiffness to 1x1 and the weight is comparable to 1x1x1/8 tube if you actually look at weight per foot among other things.
