Problem with your current stations are that they are too far away, specifically too far inland, making them less applicable vs. the LAX station.
As for being weary of a station that is not mine, surely that reasoning would apply to any station, even the ones you support?
As there is no option (I could find) to select my station of preference, I do not know if there are any better stations, maybe even the ones I know from wunderground, than the one auto selected by the app?
