Aluminum much cheaper and easier to deal with.

You do need "one size fatter" compared with copper wires. Even after that, the aluminum wires weigh less.

You ran a 3" mast for a 200a service? You are ambitious!
Was it a 3ph service?

Any issues with loosening lugs? Not concerned about the panel but what about the pan? Should I have poco pull meter after 6 months for a check or is that letting my OCD win?
