Learning where to pull/push crankbaits for crappie

[CHECrappie]

I normally double dip with two poles in my hand. Love to feel the thump. Believe it or not, there are times it just doesn't work, especially in the summer, and I want to have another technique in my arsenal.
I've read numerous articles and watched many youtube videos on how to rig, types of crankbaits, trolling speed, etc. However I can't find anything on where to fish this type of technique. Watching the videos it appears that most maybe fishing these along deep creek/river channels in clearer water. Where I normally fish, it's deepest will be 10-20' and mostly stained water. Will crankbaits work in these areas? What do I look for when starting this technique as far as lake features. Obviously I look for shad balls but is there something else? I normally fish the south end of Lake Eufaula Oklahoma. Eufaula does have deep clearer water near the dam but I've never fished that area. Thanks!

Find the thermocline, then fish flats that are slightly deeper. Also try any edge/structure/depth change near the thermocline.

This is exactly right.
