2 is fine. Here's what I did, and it's specifically aimed at CNBG. Native BG may be the same, but I'm not sure they deal with cold weather the same as CNBG. I would separate the feeders, and place them based on two situations. First, I would consider the predominate wind direction, and then have deeper water relatively close to the feeder. If the feeders are throwing into the wind, then shorter, but more, throws might be good. If not, then food will float to the bank before all the food can be eaten, and the "15 minute rule" doesn't work. If the feeder is throwing with the wind, then it will float out, and that's ok. CNBG will feed in cold water, but can be picky during, or right after, a front. If they do move out to deeper water, then they will probably move straight up to feed, and not move into the colder shallow water.
I'm assuming south LA is pretty humid, so you might want to run the feeders to empty every few months and check for clumps of moldy food. All feeders are potentially going to have that problem.
The CNBG I feed stay pretty close to the feeders unless they're spawning, or getting ready to spawn. I'm sure fish move to the feeders after they get accustomed to the throw times, but I wouldn't know how far they would travel.
