With Lil Smokies we catch both channels and blues. I've always been told if you want channel cats, fish your bait on the bottom. A blue cat feeding range is any where from the bottom to the top of the water. When we set jugs, we mostly catch blue cats. I do know we have caught channel cats at different depths also. But the majority of the times they are at the bottom.
Merry Christmas to all. May you have a wonderful and blessed Holiday season.
