Tough to say, it changes daily along with the river conditions. Pulled crawlers one day right along a very defined current seam and caught walleye, perch, smallies, etc. Went back to that same spot but the river had dropped a foot, fish were in a completely different location (more out into the current as it was weaker) and much less frequent. We left and ended up doing better the rest of the day by pulling cranks, along rock shores and flats.
Best way to find what pattern works is to try them all, until you find the one that works. If I say dragging crawlers worked yesterday, it doesn’t mean it will tomorrow. Biggest thing I’ve learned when spot-fishing on the river is if you don’t get into fish within 10 minutes, leave and go elsewhere. If its a spot worth fishing, you’ll know quickly.
