Kishels is a must, the dipsy bite can be touchy in that depth of water try slowing down to 1.9 and use any option a bit more stealthy long lines off riggers, leadcore or jets / torpedoes to achieve depth off inline or preferably big boards . I run 1 dipsy on 3 setting and next smaller size on 2 setting inside and way back in close if its all you have. So I'm stacking dipsys on both sides of boat.
