Welcome and good luck this season!
I personally don't care for trolling but I suppose sometimes it has to be done.
Have you ever been on a charter boat that trolled?
Not trying to be a salesman, but there's a good captain on this forum that runs small charters and might be good to learn from. I'm sure he'd give you plenty of info while getting you on fish.

Greg's a real nice guy and it might be a few hundred dollars well spent.
