Cables rattling in mast?
constant clankedy clank keeping you awake at night. get some pipe insulation (usually black or grey) and wrap it around the wires and slide it up the mast. Even better, if your spar has accomodations for internal slides, simply purchase said internal slides, zip-tie the wire/insulation assembly to the slides in 3-5 foot intervals and slide the whole thing up the mast. Having trouble finding slides that fit your spar, get creative, modify some track slides or just forgoe that option alltogether..
