Depends on what type of drop shotting you do. I have 2 spinning drop shot rods. One for shallower water and one for deeper water. For shallower water I use a Dobyns 6'9 ML drop shot rod paired with a Shimano Stradic 1000(white one). This rod is great for shallower situations and using lighter drop shot weights.
I fish Erie a ton so I am always fishing deeper/rougher water so this is where my other rod comes in handy- Shimano Crucial 7'2 MH Extra fast drop shot rod(new one-green and black) paired with a Shimano Sustain 2500. The Medium heavy allows for the power for deeper water and heavier weights you will use and with the XF action to still feel the bites.The balance of this rod paired with the sustain is unreal. These set up really work well for me.
To help, bring your reel you intend to use with it to the fishing store. Stick it on the rod to make sure you like the feel.
Good luck!
