Learn to convert what you have to what they have, opinions are like ,everyone has one, :-) you just have to experiment. If the fish aren't bitten I find shoals to troll over to get a real grip on where im running.I have charts for my stuff.but they are only guidelines because I run a different line.make a log of what your trolling, speed ,line,lures,ect.some time on the water is always the way to go.charters are great but you still have to put that knowledge that you learn to use,no one can catch them for you.Read,listen,search online ,watch you tube. The more you learn the more consistent you will become and at a very quicker pace we all fail to catch them every day that's why they call it fishing.If you where a captain,most have friends to help them when the going gets tough. They just do it much more so there on the fish.And there very good at it
