I would try both styles of trolling, unless you already know whether you want to run big boards or small boards. Most of us are not secretive about teaching clients how to troll lol. Once you decide which method you want to set your boat up for then you can figure out how much you want to spend and what gear to buy. But the best thing you can do is get on some boats and try them out, whether you have to pay a charter or find somebody that you can jump on and split expenses.
