I see the drop shot as clear water flipping. Just like flipping a jig, most of the bites occur on the drop shots initial fall, whether its deep water of shallow.. I believe that the fall rate and the allowing of the bait to come in contact with the bottom as being the most critical aspects of the drop shot. I almost always use a lite sinker such as a 1/16 ounce. The only real time I drag the drop shot is when I feel structure on the bottom such as a brush pile or a drop, then I usally pull the bait tight then let it fall back down working my way through all the limbs. I fish brush piles usually with a regular size 2 offset wormhook. I see alot of people thinking that you need a circle hook to be effective. I dont see that as being true. 90% of the time I use the regular offset worm hook. You dont get hung up as much with the texas rigged drop shot. As for baits, I have caught fish drop shotting small robo worms, tiny brush hogs, tubes, grubs, lizards, beavers, trick worms, curly tail worms and senkos. If you have a lake with deep grass try longer leaders. I tend to use a 6 to 10 inch leader but with deep tail grass, I try to determine the height of the grass then 6 to 10 inches above that. I have used leaders up to three feet around grass and at times that is very effective. My favorite drop shot bait for this type of situation is the beaver.
