Begin building your drop shot rig by spooling up with a braided main line to support long casts and provide you with enhanced sensitivity. Select a braid with a smooth finish and the thinnest diameter possible; these attributes will help you cast the drop shot rig far away from the boat and reduce air- and water resistance as you fish it back to the boat.
Fluoro’s low-stretch characteristics enhance the sensitivity of the drop shot presentation while maintaining an exceptionally stealthy presentation at the lure or bait. A good general length is around four feet of leader, but in ultra-clear water or when dealing with line-shy fish, you may need to go longer.
For simple drop shot rigs, I like to use a bell sinker, with enough weight to keep my rig on the bottom in the face of wind, waves, or current. Carry a range of weights, from 1/8 oz to ½ oz or more, depending on the depth range you typically fish.
