Nice experiment. From my understanding of the results, it looks that some testers explained characteristics of WYeast that other testers explained as characteristics of White Labs. The differences are minimal and basically boils down to personal preference. My preference is White Labs only because it is all that any of my local homebrew stores carry. I've only had 1056 on a couple of occasions and thought it was good. I'm also really pleased with 001 as I am with all White Lab strains that I've used.
On a totally different note, I did pay to have a couple packs of 1450 sent to me
I've never used it before and am looking forward to fermenting an imperial hoppy amber with it!
