This is what someone told me ...

Minnows will get a bite 75% of the time if the fish is there. If you can find fish on the bottom with depthfinder then use a typical drop shot rig like I used in this video. I like a 1/0 gamakatsu drop shot hook. I use 15# braid with a 10# flouro leader. I use a cheap 1/4 oz casting sinker. 1/4 oz is good for 15 ft to 25 ft deep. If fishing for suspended fish I'd put a 3/16 or 1/4 split shot 2 ft up from the drop shot hook on the end of the line.
