#3 is the easiest but I am worried about open wire feed-line coiled,
thoughts please!

Adjacent coils of parallel feedline should never be located
very close to each other. The minimum spacing should be a
few times the spacing between the wires.

What I do is use a dacron messenger line. For instance, if
a knot is tied in the dacron messenger line every two feet
and at each knot, the length of the parallel line is four
feet, a transmission spiral will result where 100 feet of
ladder-line can be spiraled into 50 linear feet of messenger
line. The ladder-line can be attached at the knots using
black nylon tie wraps. Hope this is understandable and helps.
