What do you use while jigging? Do you only catch trout while jigging or salmon too?

Any aqua fly combination is good on michigan. LBB/ mistake green is one of the best for me. Was just out of kewanee 2 weeks ago and it was anything but what its usually like out there. 85 percent of our fish came on boards. 10, 7&4 color. Copper was junk. Riggers and dipseys took just a few hits. All but 2 hits came on spoons. Usually I run almost all flasher flys. Best spoon colors were glow bloody nose, pro glow blue ladder back and natural born killer. Landed 18 for about 23 on the weekend with 6 over 15# 2 over 20# biggest was 22#

I have two 10 colors one 7 one 4 and one 2 color spooled. If fish are 20 to 40 I will run the 4 and 7. How deep of water are they in? 60?? Or farther out in the low 100s? What bottom depth should I target? Thanks
