Big weighted Sculpins are my go to. When I say big, I mean as in 2" on the small size up to 4-5" on the large side, often articulated with a trailing hook. Natural colours when the water is clear, as in olives, light tans and browns. If the water is coloured then go with all white, white/grey and or white/black rabbit strips (all with some form of flash), as in the Dolly Llama:
If you are tying your own, and do not want to tie the articulated variety, a zonker style tie works well, with contrasting rabid top and bottom, like this:
Also make sure that you make them heavy, with lead wire around the hook shank and/or big dumbbell eyes or sculpin head. If you are not touching bottom on the swing, it's not heavy enough.
You can also use beaded leeches/buggers in black, brown or olive and various colours of egg sucking leeches.
