Deeper deliveries on inside lines, longer but shallower on outside. For leadcore I use line counter reels so I can keep track of distance back so not to violate that principal. For two per side, I might run a 5 color on the outside and a seven or eight color on the inside. The five color will be let out further to extend 10' beyond the inside line. Mark on each reel the distance to the end of the leader to make it easy. The inside line gets let out + say 20' of backing so the knot is in the water. The outside line is set out + say 70' of backing to extend beyond the inside bait. You could put a leadcore on the outside line and a copper on the inside line. Same with divers. A mag dipsy on the inside line and a standard dipsy or a slide diver on the outside diver.
