The flightcases in the "Advantage" - version
are different because all flightware material
consists out of mounted parts, like
mounted locks, mounted handles, etc...

Advantage flightcases are usually made out of
thin plate, which makes them
easily to transport, and extremely light.

"Pro" flightcases have sunken flightware parts,
such as built-in butterfly locks,

These are usually made out of 10 mm plate, but other dimensions are handled as well, suiting your needs.
