I went West Coast in '05 as well and got pretty lucky, I got decent stick time in both the T-34 and SH-60B. Unfortunately, only the Marines got to ride in jets, but the guys running stuff for us did a good job of making sure the rest of us got to fly in the other two.
I'm pretty sure they still go with whatever coast you live near, but if you can find someone who lives opposite coast to switch with you (I did this) it's not a big deal to do the paperwork. I really enjoyed San Diego, and from what I understand, there was a bit more hands-on experience on the West Coast in '05. Either way, it's a great experience and one that most people never get to have. Enjoy!
