I played with dropshotting the past few years and from my experiences it was best when fish were suspend and spooky, or shallow pressured fish and you wanted to target the bigger fish. I like to use a #12 or #14 hook, tie it on with a Palomar knot, and leave a 4-8" leader to 1or 2 bb sized split shot. I used allot a different plastics on my dropshot but the 2 that worked the be for me was the powerbait wiggler or the Little Atom Nuggie.
