I use the CA select organic all the time. It's my go to base malt. The only problem I have with it is that while yes, it is grown in Cali, it is also shipped up to Washington to be malted and then shipped back down.
If your aim is using the most locally GROWN ingredients its great. If you are after the LEAST travelled ingredients then the WA select is actually probably your best bet as it's grown close to the maltings.
but overall, I think it's really nice. I am not prepared to make any specific statements of the differences between it and the 'normal' great western pale malt.
