Here in Florida I only dropshot when shallow if I know fish are in a negative mood and I am confident they are in a piece of cover I can target with a small finesse bait and I usually barely work the rod and just wait for something to pick it up...
I also use it when I have a muddy bottom which is often since a shaky rig or even a texas rig is frustrating but alot of time fish are suspended this time of year and if a place gets high pressure or I am going behind a few boats on a shoreline, I will power shot instead of flip a jig or punch bait into cover. I find the dropshot to be very effective when you are near fish, and it is a bit boring, however, you can work it faster if you use the hooks with good swivels like the vmc or gamakatsu drop shot hooks to elimiate line twist. If you get line twist you are probably shaking too much, I don't shake much, the right baits move on their own....Baits with ribbed bodies, boot tails, ribbon tails, or floaters will move on their own, just make sure you can feel bottom at all times.
I love the Mister Twister 5" poc it worms I grabbed on clearance at dicks, they are soft, ton of action, translucent, and also the damiki baits are good, Gulp floating minnows, small GYB Ika's, trick worms and senkos wacky rigged, or for power shotting, I like using the keitechs, trigger x minnow baits, gitzit flash tubes.
I do like the split shot, mojo rig the best, Another quick set up is to leave a 18" tag end on your regular soft bait of any knid and crimp a large split shot on the end of the line or simply use a true floating worm with a split shot and you kind of have a drop shot...If you like moving a bait then drop shot probably not the best, c-rigs with light weights and lifts will catch fish suspended and keep bait up in the column, I catch fish on modified c-rigs with heavy weights for loud splashes when fish are active but have lock jaw, and it often works in 2-3', same as drop shot with 1 ounce, but overall I use mainly 3/8 drop shot weights and vmc swivel drop shot hooks and nose hooked baits have best action in my opinion, I will try crazy stuff, sometimes a lizard suspended in the water works but nothing is better
for catching spawning fish if you don't sight fish than the drop shot. Find the flat they are on, and simply cast and move it maybe 3' every minute, few taps of rod, and a bait with crazy action like the damikia air craws or small minnow baits I forget what they are called...
