Hmmmm maybe those fish would bite a jig fished properly. If you can see the fish then they may already know your there. If you add visible leader . to big of a bait profile, the wrong/to much scent , to much lead, wrong color yada yada it can become frustrating. Next time you can see fish try fishing smaller baits without scent, jigs under a float, or a single corky and a split shot. Good luck next time , and thanks for the report.l
