I saw someone mention trolling spoons behind Luhr-Jensen jet divers. I normally will not use spoons because they twist my line. With the jet diver, I only used 6 feet of mono. And the diver delivered the spoon to 20 or 30 feet deep. I used a blue/white little cleo.
The setup seemed a little clumsy. But I have a long 8'6" rod that is pretty stiff. I brought it just for this rig.
I made a few passes and was about to switch to a taildancer. Then... I caught a lake trout. We trolled taildancers and the spoons/divers. The spoons caught nearly all the trout.
I just bought a few more...
