starting to get into drop shot, just wondering what is a good bait? Also how long of a leader from hook to weight

Get five dinero, zoom finess or trick worm, meat head...you can really throw a lot of different baits on a drop shot. Those are my favorites though.

The tag end will be something your'll have to figure out on that day your out, but i'd start at 18" and work your way down to 6". I like to use robo worms most of the time ,but found that a shad body bait is good to. I personal think yamamoto shads are very good, So are there cut tail worms.
