I probably use a c-rig most of the time, you can really work the sweet spots of the ledge a little more slow. But different times of the year I will change it up often. Here are my favorites.

When fish are active, and I can see balls of bait fish - I will always start with a crankbait. When you get into them on a crankbait, it is as much fun as you could have fishing ledges, and that is good, you will need the adrenaline rush to keep you arm from wearing out.

Rapala Dt-16 in parrot, or Lucky Craft in Blue/Char - Fish here seem to love that blue and char. color.

Jigs in all sizes depending on depth and how steep the drop of the ledge is. I usually stick with Green pumpkin, or green pumpkin and blue. Some orange in the skirt seems to help some.

Big worms. Usually in big worms I will stick to plum colors (I just have better luck on reddish/plum colors), but I know quite a few people that stick with wartmelon, and green pumpkin - some purple flake in those will sometimes do the trick. As far as brands, there are a ton of good ones out there Baby Huey's are my favorite, but I also really like Charmers, Todali Tackle, Net bait and 10" power worms.

Carolina rigs - I pretty much only throw Charmers timber pups. Every once in a while, I will put a large worm on it.

I also have had some luck on the big spoons in Chrome color - but still need to gain some confidence in those. I know some people that swear by them, but I have only got into them good on a few occassions with them.
