When I'm trolling with Rapalas and a diver or rigger do I need to have it tied on with a rapala knot, palmor knot or attached with a swivel? When using cowbells, how far back do I have my spoon or lure? What type minnows should I get shinners, pike minnows or saw bellies? Sorry for all the question just new and want to do some things right hope you guys and your knowledge can help
