This year we decided to use 80-20 for our robot frame as it was great for prototyping, moving stuff around, and very, very strong. However like many teams it ate up weight, parts shifted (a lot), and was a hassle when we ran out of sliders and brackets. Team 234 said in their swerve drive implementation conference that 80-20 is a great prototype, but aluminum box is better for the final as it is lighter and parts don't slide around.

Did you guys drill through the extrusion when you finalized part locations? That basically keeps all the advantages of 80-20 and takes away the sliding problem.
