Your favorite Cali Chardonnay?

I loved listening to the different perspectives on the California Chardonnay podcasts (, if you haven't listened!), and it got me thinking about my own preferences and the availability of different styles.

For example, I can't believe that just today was the first I'd tried Stony Hill from Napa. They blew me away. Other favorites include Sandhi and Hanzell. What are your favorites (and why)?
