I was running 2 downriggers, 2.5 mph give or take, using a silver/green J-plug, & a green & yellow plug, also tried a red and white one for abit. Tried setting lines anywhere from 15 to 25 feet down. What's a good channel to monitor for info? Tim you are on the money about watching out for everyone else, boats everywhere, you almost need a nascar spotter out there, pretty near got ran into the wall a couple times.
