I was wondering if it would be better to buy a HI yellow lense or a persimmon lense for some of the conditions I ski in. I do quite a bit of night skiing and skiing in crappy weather conditions out in Utah (Overcast, snowing, flat light). Will a persimmon lense be good enough or should i pay a few extra bucks for the HI Yellow. I have a black iridium lense already for sunny days so im not looking for an everyday lense. Thanks for the help.
