I have only fished with my own homemade worms for the past 33 years. My drop shot worm of choice is a 2 1/2" worm or 5" thin curly tail pinched down to 4". I mostly drop shot for smallmouth but occasionally hit a few largies on them as well. Favorite colors depend on water clarity and time of year. If trying it for walleye go for white or something chartreuse. For bass I like watermelon, motor oil, shad/minnow colors or pumpkin seed varieties.
