as far as depth, i wouldn't vary much between 8-15 feet depending on lake/river/structure. lure/color has too many variables but small swedish pimples, 1/32 jigheads tipped with chopped minnows, maggots, pinhead minnows all work well but depends on the bite. as far as line...2-4lb works best, but with northerns around i tend to use 6lb. test for a little more toughness. there's so many techniques that work for perch, and to cover this in a single post is impossible. hope you get some good tips. grumpymoe
