Copper is best where it will not be subjected to bending or flexing. Has the
lovely property of becoming brittle as it is worked. Probably both surveyors
were correct in their concerns.

Copper for the long fixed runs, rubber or braided rubber for where it may be
flexed. In my opinion.

I don;t think copper for propane is acceptable for boats in the US.

Mandatory in the Netherlands. The only place where rubber is allowed is
the
shortest possible run from fixed copper to the regulator on the propane
tank.
