Wow, great trip report! I'm really sorry I didn't get a chance to join in the merriment, but my schedule simply would not cooperate.
I'm glad you got a chance to dive the Peace... it's a real jewel in the SoCal boat fleet. Best ship out there. Their food is incomparable, the DMs are friendly, helpful and incredibly knowledgeable, and hey, they pump Nitrox and offer HP fills. Even the bunks are reasonable! (On multi-day trips they have a washer and dryer, too, and can give you your DS undies in the morning still warm!)
There are a bunch of boats down here that have on-board compressors, although slightly fewer that can do HP fills, and only a handful that pump Nitrox. I really feel for those that don't have any compressors and have to lug multiple tanks, though!
Here's hoping I can join up on your next trip down...
