For lakes and pond trout:A variety size of Jointed Rebels,floaters and divers.
For lake trout:a lake clear wobbler or a chrismas tree rig with a big chunk of nightcrawler behind,trolling deep or depends on the water temp.
The rebels I use are black on top and silver on the bottom and closely resemble smelt.
Trolling with a fly rod:I have success with a 1 1/2 inch Mickey Finn
