something else to try is a slip bobber, if you have the fish marked at certain depth , put the jig at depth you want, along with a light jig I have found as the water cools I can sometimes leave it set still and they will hammer it, or fish it how ever they want it. I will jig it with the bobber or swim it very slow. I recently was casting from bank catching them 10-12' of water as evening approached the moved shallower and took the bait on bobber in 6' of water with the bobber.
Philippians 4; 13, I can do all things through Christ who strengthens me.
