I use size #1 dipseys. 8" snubbers with 20 pound mono leader about 5-6 ft long. I run the dipseys usually without the plastic ring. Colors dont make much difference to me. Dont think the fish care much but I dont use loud colors. I use 4 jet divers on each side also on the boards. Blue on one side and red on the other. Maybe try 2 diff colors of dipsey. One color on port and another color on starbd. I do this to help customers from getting mixed up. I also put blue tape around the rod handle to match the jet diver. If I run crankbaits on one side and jets on the other, I just remember which color is jets. Try to make the setup as easy as possible for customers to use. Check the diver chart for dipseys with or without ring and the line size on the reel. I use Power Pro 30 on all trolling gear.
