Hi, First time using the ladder line, Please offer your opinions?

I have the 50 foot tower, it is right outside the shack window, so will be
drilling the two small holes in the sill, then fishing through approximately
12" or 18" then replace the spacers to keep the distance between the leads
constant. That leaves the remaining 98 feet outside of which I need a
distance of approx 35 or 40 feet of the ladder line to reach my center fed
80m or two wires 66feet each leg. What are my options with the left over 50
feet (approx) of ladder line? Coil it up? Cut it? And what are the rules
about keeping the ladder line away from the tower and steal guy wires that
are not insulated? I only want to do this once now and first time using the
ladder line, all suggestions appreciated, thanks.....
