2 1/16 oz jigs trolled at .9 using 4 lb line will get about 10 ft deep
you can add split shot above top jig an get the depth you want about a 1/16 oz sinker will do it .IF you heavier line adjust sinker size find water depth you want
and troll across it till you start to drag adding and removing weight
i have found trolling .9 to 1.0 the best speed for the lake i fish using a gps .
