As a sailor, my major concern with line, (rope to non sailors), is chafe.
I don't like either of your choices for that reason.
Much prefer to use pad eyes and thimbles for the line.
Mount the pad eye with 4, 1/4" bolts, then use a clevis to attach the
rope thimble to the pad eye.
You don't need S/S hardware that you would find on a sailboat,
galvanized will do a good job.
