I did brew this and I used American Ale II WY1272 yeast.
Came out really nice but its not a clone of fat tire. It is actually better. The flavor is sort of similar but stronger and more interesting. I can detect some yeast esters from the 1272 so if you are not a fan of esters be sure to do a big starter to reduce those some. I pitched out of the smack pack without a starter.
The color is noticeably wrong, probably 2 SRM too dark or so. This may be because I used Pale Malt (3 SRM) instead of 2-row (2 SRM).
Really a nice recipe though that I like, my BMC friends like, my craft brew friends like it, and it has been well received by pretty much everyone that has sampled it, even my SWMBO's mother!
