Almost physically reacting negatively to one kayak maker's and designer's sculptured, beaded, festooned kayak rigging, I thought at the time that a most simple approach would be to temporarily wrap the centre part of the bungee, line, or whatever around a 3/4" dowel, saturate with CA or epoxy over say 2" [ 5cm], let setup, and remove.
Would work as a line raiser and might be unobtusive too.
Anyway, a variation of this would be to use a small section of the same line, wrap around a dowel of the line's diameter, saturate with setting glue, remove and cut off a 1-2" section and use that - that'd be another unobtrusive approach.
anyway, another line of thought
