Replace it. If one's doing thousand$ on the trip, don't let a poor shooting/floating/potentially damaged line hinder ones efficacy. Kings don't come easy, even in Alaska. With out for sure knowledge on the conditions one might encounter, I'd suggest a Skagit set up with a full array of heads from floaters to deep sinkers.
If your using a guide/outfitting business, quiz them for suggestions. If they're professional at all, they will know.
Good for you on the build. Just wrapped up a 16 footer myself. Might still do some feather inlays, but it's ready to fish.
Good luck,
