+1 on the wool, and lighter weight would be best for your climate as far as I know (not that I have ever been there). Check places like Sierra Trading Post for good deals, and even eBay (I've found a lot of Icebreaker stuff there--some people sell salesman's samples on eBay and they go for much less than you would normally pay). As for fit, I will say that the Icebreaker tops are pretty long for us shorties but I don't find it to be a problem--would much rather have some extra length than have it be too short!
