A four rod salmon spread is pretty simple. 2 Talora rigger rods 8'med. and 2 Talora dipsy rods 8' MH. all four could be fitted with Shimano Tekota 600 line counters for the divers, line counter or not for the rigger rods.
1000' ft. 30# wire for the divers, 20# to 30# mono for the riggers.
Now if you get into spring/summer kings, spoon rods, trout rods spring/summer, leadcore, copper, mono/power pro divers you may accumulate over 40 combos
