We start fishing mid may off Brocton Shoal and troll from 20 to 40 ft of water this year we do good on three colors with husky jerks. This is the same time of year they catch them at night on the reefs. We target these fish directly off these reefs deeper during the early morning and late afternoon. Early June and into early July we catch fish suspended in the top 40 ft, occasionally in the top 15ft sometimes over a 100 ft, just depends on water tempature and were the bait is. When we first started using segmented cores it was 3 colors, 5 colors and full cores. We still catch alot of fish on full cores directly off the back of the boat. Sometimes only letting 7 colors out, one on each side. If you are just starting out I would get two 3 colors and two ten colors. You can run the three colors off the inlines and if the fish are 25 ft down add two ounces off wieght after deploying the three cores with a snap wieght. We still do this, I run three inline boards per side, say three five colors on one side and three three color on the other if the fives are out producing the threes we simply add 2 ounces on the three colors therefore essentially running six baits at roughly 25 ft. If you get a fish on the outer board you just need to let him drift back a little before cranking in just taking your time.
