i know you are technically supposed to use black iridium unless its sunny out but i used it all last season, even night skiing and it worked amazing. pink iridium seems pretty good all around too
the ideal is having 2 lenses, a black or fire irid and a hi-yellow. you'll get maximum visibility with that combo but it's a bitch to change them a lot when the weather's going nuts
A little off topic but not at the same time.
are the green lenses for POC Lobes decent for an all-day-every-day do it all goggle? the poc site rates the green at 36% VLT
i used a blue iridium last year and it worked great. now im using a grey plarized/fire for sunny days and pink iridium/h.i. yellow for nights and overcast
