I like to use the same size poles out the back (9' Roger Gant). Side of the boat I like longer poles 10',12' and 14'. Tangles are a part of life when you L.L. I would suggest start out using the same style jig head, same body( Bobby Garland Stroll'R ) is the best. A good spinning reel helps alot. I believe line size, speed and jig size are the #1 way to determine trolling depth. It takes some TOW.
Get ready to retie a TON but I love it.
