Shade, When you run flashers off of the copper, I go 20' per 100' of copper. Spoons I follow the 22' per 100' of copper. 45lb copper will run a lot deeper than 30lb. copper. 300' leadcore (10 colors) only runs 40 - 50' down depending on brand and lb. lead, copper will get you 60 -66' down with the same amount of line out.
