Hey LGHT,
The typical Carolina rig application is for wide flat areas that may be holding stationary fish, or in the case of the typical western impoundment, flats, (Deer slope, at Casitas) round top, high spots,( some of the shelfs and pinnacles at Mead), broad saddles or river shoals, (the California Delta). the typical approach is to long, cast downwind, and work a wide area slowly (boring!). The bites, because of the leader are usually subtle or pressure bites, (one of the hardest things to learn about the technique) which again is one of the reasons many eastern rigs are set up with such heavy weights. I spent an entire year trying to learn this technique and finally concluded that it has limited use in the steep flooded canyon impoundments of the west (as opposed to the dammed and flooded river bottoms of most of the rest of the country.) and it just bored the sh-t out of me. I did not catch many big fish but saw it's tournament value as a five fish technique.
All that being said it is an ideal bay fishing rig. Because most of the SoCal harbors and bays are shallow and have extremely poor natural inflow and outflow, sand and mud are the primary bottom strata and algae, moss and eel grass the primary cover. Perfect for Carolina rigging!
hope this helps bodfish
