Well hot damn. You'll fit right in now. Goggles aside, you probably wont regret much. I actually found the phenom to be a little larger field of view than my old I/O.
I am on a set of I/Ox this year, and they are fairly large. Best goggle I have used to date. Very fog free.
I upgraded my phenoms to the Io/s. I've only gotten to ride with them once so far, but they were badass. I never had issues with blind spots, or any hidden terrain. I love the swap-ability of the lenses too, although haven't had to use it yet.
