Like mentioned many times on this and other boards, both of you go out with someone who knows trolling, you will learn more in one day than you can experiment and learn in many years of trial. There is lots and lots of great info if you do a search on this and other web sites. If you want a few articles that might help, these are old and I have updated them but this site won't post anything I write anymore since I haven't been a member for a long time. I never charged for my articles so I just don't get why they won't let me update them or post some new articles. But anyways, If you find things you have questions on just PM me and I will help the best I can.
