I've had a lot of experience with the drop shot for smallmouth bass, in a deep clear water reservoir. I've also had decent success using it for LM bass when fishing from shore. I've only been using the drop shot for crappie for the past 2 seasons, both drifting in a boat and some shore fishing.
It is a very deadly technique, when employed for just about any species and in almost all situations - from boat or on shore. As long as you understand it's limitations; it is not a search tool and you'll be doing a lot of re-tying if you use it in snag infested waters. And, it is most effective in clear to lightly stained water, as it is surely a visual presentation. That being said, once you pin point the crappies position, it can be very effective for you, as I've been finding out!
BG plastics are usually at the top of my list regardless of what platform I'm presenting them from. I do not use the drop shot with a jig head however. Not needed. Just nose hook the plastic. Use a Gamakatsu Split Shot/Drop Shot hook, size #2 works for me for any species. When drop shotting for crappie from shore, I use a 1/8 oz. sinker; a 1/4 oz., or more, from a boat. Hope this is of some help.
