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.
So I ended up going with gore-tex everything and a very lightly insulated pants/jacket. Even with that, I'm still finding it a little warm after a few runs so far, but not too bad.
The biggest thing was actually the goggles...I didn't expect to upgrade those, but my RC36 lenses (36% VLT) had me riding on brail most of the day. Just got some blue sensor mirror (70%) and love them...big visibility improvement in flat light. I went with the smith phenom frames to save a bit, and I kind of regret not going with the I/O and getting a larger field of view. Not too happy about the blind spot area on the phenoms, but I'll manage.
let's not talk about it
