Following on from the WT post above, I was curious about the Buffalo Trace range. It is also something that is unavailable in Oz, so I'm taking advantage of the folks bringing some back. Problem is I can only get 1 (customs etc.)

I'm really looking at the higher-end stuff, cause I can order the BT and ER10 later on. If tossing up:
Eagle Rare 17yo
Rock Hill Farms
W.L Weller Centennial

What would be your pick (as a foil to my other request of Elijah Craig 18yo)
Are all of these readily available in most stores in Calif or SF? (with the exception of the Stagg)
