R, the Carolina rig can be used all year on lakes, rivers and ponds.
Are you asking us how to rig the Carolina rig; what baits work best; or when and where to throw it?
The set up is designed to keep the 1/2 ounce weight on the bottom as the worm or lizard follows on a leader about 12 to 18 inches. This allows the bait to move without being impacted by the weight.
Lizard's are a bass' favorite snack and they will hit plastic lizards on a C-Rig. Finesse and trick worms work well, too. Some guys use a crankbait. Others creature baits. Anything goes. It's a Carolina rig.
Cast, let sit for about 10 seconds, and then drag it slowly back. You are going to do two things: First, feeling the bottom for rocks, grass, wood, tires, and in New Jersey, dead bodies, etc. Second, you are actually fishing for the bass with your bait.
Now, to be different, I use GLASS BEADS. Clear glass beads. I also have some "weird" beads I purchased at a bead store in order to have a different "click" from the glass and red plastic beads. Bead size is up to you, just make sure they protect the swivel knot and are not too large.
Buy your beads at Joanne Fabric as they are less expensive then in a tackle shop or via the Internet and they have an excellent selection.
As for color, as stated above, I use clear beads. But the glass cut reflects light better than plastic beads which is an advantage. I usually throw a green pumpkin with black flake Zoom lizard or a Junebug Zoom Trick Worm. Since you will be on the bottom in darker water you can always dye the plastic's tail in yellow JJ's Magic or another brand.
So get your "heavy" rod with your baitcasting reel spooled with 20 pound test fluorocarbon line (some use mono for this presentation), a 1/2 ounce weight with a strong swivel of the size of your choice, your two glass beads and then add about 18 inches of your 12 pound leader with an EWG hook size of your choice depending on the size of your bait and start casting.
Put a small spot of fast drying glue on all three knots to help protect them from coming apart.
Have fun and let us know how you do.
