Peanuts work well, also cowbells. In Ludington we target them in front of the (PSP), Pumped Storage Project, aka "the projects", 60'-90' fow on bottom. Slow boat all the way, use sea bag too if necessary, best speeds historically, 1.2-1.6 mph on top. Watch thermatroll and keep top speed consistent with bottom speed as close as possible. Speed is critical, along with bait fish marked. I typically use longer leads of 8'-12' behind the ball.
