Hook the bait in a strong place, depending on the bait, get your weight close to the bait, a sliding weight comes to mind.....learn how to cast with your spool tension at 0, and lastly, learn to cast softly. When I say softly, I mean avoiding snapping action. It's more of a side lob. I hope that makes sense....it comes with Practice.
A long rod definitely plays a part too.
If you can either quickly or quietly switch out shells, you can bring home almost anything.
