toad i set up in deep water year round. when we trolled we stuck to water 12 to 15 ft deep, which is a good depth for trolling in the spring and fall. with my set up 16th oz jigs run about 8-10 ft deep, 1/32nd 4-6 ft. trolling and nightstalking is two entirely different ways of catching em. my take on it is if you gonna spring or fall troll id say stay in water 12 to 15 ft and nightstalking stay in water at least 20ft. i think in a deep water setup the bite is better cause they got more of the water column to play with in an excape attempt and their options for excape narrows considerable in shallow water and they nervous about coming under a boat in shallow water. if i was gonna go shallow at night, id use slip bobbers and get baits out away from the boat.
