I'm a junior LAX 320 lineholder (~65%) and Ive been dropping almost everything except for holiday trips. After clearing my schedule as much as I can, usually I pick up out of base trips in DFW (where I live), but sometimes I rebuild with good LAX trips that appear in open time. I just drop the green trips (if any), post all the red ones to automatically drop if someone else wants them or if they turn green, and then trade the others around as much as possible until something turns green or I can get trips that fit together well enough to minimize my commutes. It's not too hard, but can take a few minutes each day to check what trades are available since it continuously changes.
