It's nice to get feedback from guys running the same helmet / goggle combo but honestly the best thing is to just try them on if at all possible.
I've seen some guys say brand "A" helmet is awesome with brand "B" goggles but when the next guy tries it out, the combo is just okay or sucks.
Reason being, everyone's face, including cheek bones, nose, eyes and overall shape are different, hence a different feel and fit.
When I purchased my last helmet, I just took it to the dealer and tried a few different goggles until I got the best fit to the helmet and to my face. Ended up staying with Scott but the 509 Sinister wasn't to bad. Also tried a set of Oakley's that fit awesome into the helmet but when I put the helmet on the goggles didn't feel right on my face.
Anyways, like I said check around and try a few combos if possible, you be happier in the long run.
Good luck.
