Occidentalis

Raspberry Pi-Soliciting quick opinion from experienced users

I got my Model B Rev. 1 in the mail yesterday and SD cards are cheap enough that I'm just going to buy a new one.  What's the optimum size card for the new Adafruit Occidentalis distro (http://adafruit-raspberry-pi.s3.amazonaws.com/Occidentalisv02.zip) if it unzips at 2.6G?  4, 8, 16?  I probably won't go 32 right away...
