The reason for my setup is simple. I have a strong, sensitive, abrasion resistant main line with the heavier fluorocarbon. The lighter, mono leader is more buoyant and gives the bait better action. A few more things to consider are rod, reel, and hook selection. I prefer a 7'6" MH/F rod and a high speed reel. I built mine on a Rainshadow REVC76MH and paired it with a Revo STXHS. I almost always choose a traditional round bend worm hook over an EWG hook when fishing the C-rig. I just seem to get better hookups with the round bend hooks. There's a lot more to fishing the old chicken liver rig than some people realize, and I suspect that is why a lot of people don't do well with it. Give my setup a try, and see if your Carolina rig game doesn't improve.
