I have set a couple guys trolling.Yes 4 line counter reels the way to go.Diawa deadline for around $110 bucks each and you can get wilderness trolling rods for $20 each.Mono is line to use,we used mono on dipsey for few years and you can get by with that.I would get 4 inline boards to start also.We troll worm harnesses most the time with the #2 tadpoles and works great.You can get some spoons and they work with the tadpoles.If going to be fishing early or late enough to use cranks,I would get stock color bandits first then add the custom colors as you see fit.Must control your speed,bags cheapest way to do on most boats.Good luck and keep reading these posts to get better each year.
