The best on the market: Off Shore OR-12's. (bigger ones) the smaller ones help detect really small fish better - but for the majority of my crappie fishing I prefer the OR-12's. Accept NO substitutions either - you will only need to purchase the boards one time if you buy Off Shores. To answer your other questions - I use 10lb Trilene XT - it is the line they use for all of the crankbait dive curves. As far as jig size is concerned - whatever you usually use - just clip the board on where the line in one of your standard trolling scenarios enters the water. When we took second in Florida this year - we were using 1/32 and 1/16 ounce jigs - but using in-line diving weights called tadpoles. Keep the questions coming!!!
