Everybody claims to have the answer but unfortunately one persons eyes are going to benefit from yellow or rose, and another person may not. It's really a trial and error process just like getting a specific prescription for regular glasses. The local shop owner here in Bend is a former pro that now coaches for the redbull grom team and when I addressed him about this issue when I wasn't happy with the oakley hi persimmon and hi yellow for the flat light at Bachy, he said his eyes see best with Dragon rose lenses. Me not so much. More than half my season is spent in white out storms and flat light below the tree line. I need visibility. If you are only going to get a handful of days, it may be hard to accurately pick out the best goggle for you. Either way almost all goggles now come with a dark lens and light lens which is helpful. Whatever brand you decide to go with, look at their lens chart and get the lens that lets the most light in possible without buying clear. A good low vis lens will enhance whatever light is available to maximize contour of the terrain.
