I think you'll be happy with any of those actually. Haven't used the pub ale, but I bet it would be great. 1056 and WLP001 (cali ale) are the same strain and are exceptionally clean. Nottingham is another clean yeast, but more british in character (but MUST be kept cool during fermentation, think 59-62F). Really, any should be great, but if you can control temps go nottingham or Pub ale (just because I'm curious).
I can't be arsed to keep up this list of what's in the fermenters, but hey, check out the cool brewery I'm opening up!
