dont be skeet to try different depts and amount of line out and here in tn i troll till i catch a fish and will keep running over the same spot using the bread crumb trail on my fishfinder,and sometime i catch a couple fish every pass once i find them.when i first started i would troll the edge of the river channel and only caught 1 crappie in a month ,and then i started working creeks (channels and flats)and started catching fish and most fish are now crappie.another thing i use the 200series most of the time when most people said use 300 and now they are what i prefer.dont know ur waters but i have been catching fish in 10-12ft of water with 40-80ft of line out
