I throw the drop shot and catch more big fish around here on it than anyone i know. I throw it deep, shallow, into current, into grass, around wood, under docks, clear and stained water. @TnRiver46 has seen a lot of drop shot fish this summer A few things to consider--
-throw it on a 7'4 rod so you can sling that thing
-3/16 or 1/4 should be about the biggest weight you ever need
-use light line, 6-8lb
-throw zman trick shotz, they float perfectly horizontal
-use a chrome sinker, this little extra flash can catch an eye
-rotate through a lot of baits and colors, you can get them fired up and clean up a school with a drop shot simply by changing baits
-do not set the hook. reel tight and lift
-you really need at least 3-5 ft visibility for it to shine
-10-12 inch leader
-if you know the fish are there, spend some time & work different angles. the drop shot can convince non aggressive fish to still bite
