10 to 15 behind the ball is all you need. No different than a bait behind a dipsey. Keeping them choked in like that keeps them from coming up in your dipsey spread as well. Just remember if you are running diving baits, they will be below the ball so adjust your ball depth accordingly. BTW, there are fish at 02 line out, 38 to the 50, no need to go 15 miles. We had 4 tickets between 8:30 and 11:30 on monday. Big boards, flat lines, dispeys and 'riggers on harnesses, spoons and cranks, speed 1.9. If your on active fish, everything is working. Last Fri/Sat/Sun out of Conneaut we had marginal results, North of the perch pack 04/05 between the 31 and 35, lots of good marks, but not real active. Took fish on just about everything we ran, but they were not active like the fish in Ashtabula over the weekend.
