Rat-proofing cables for long-term install

["Jeremiah Moore" jeremiahmoore99]

Hi -

Has anyone dealt with ratproofing some cables for a long term installation?

My project involves four XLR-XLR cable runs of about 20 to 50 feet.
 They'll be in place for 6 months.  Covered by a roof but open to the
exterior and salt air.  (near the ocean, under the foot of the golden gate
bridge actually.)

Ideas I'm working with:

1) irrigation pipe, of sufficient inside diameter to run XLR connectors.
benefits:  relatively cheap
difficulties:  stiff / inflexible.

2) metallic flexible conduit
benefits:  designed for the purpose; easy to work with
difficulties:  expensive

Any other approaches anyone's used?

thanks-
