I also live in Southern California and just purchased my first skis at the beginning of this season. I have been skiing my whole life but have been renting up until now, so I kind of knew what i wanted. I am 5'7" and weight 150 lbs. Not sure if this is exactly what your looking for but I went with the Armada Norwalks. Not sure where you are located in Southern California but Armada is based out of Costa Mesa, California and their skis are made in Austria.
The Norwalks are said to be a all mountain / powder ski, and after spending this season on them i can honestly say they fit the bill. I absolutely love them! Awesome in the back country and powder but also able to carve up groomers when you want and they feel natural. Check them out they are a great ski! (If you like astronauts).
