Ok, now I sound like a broken record, but just having replaced *all* my deck hardware after painting #56, I used both aluminum plates and starboard because I had both. I much prefer the starboard - cheap and easy to work with. I plan on backing my jib tracks with that also. As for backing under the toe rail, I am not sure how bendable the starboard would be... but that is certainly where I want to put my genoa tracks.
