Polarized on Gen 3 definitely has a different curvature for some reason. I have no clue. Anyone else have any thoughts.The "New Frogskin" was an 8 Base Curve. Not sure on 2nd gen, but I believe most of the "classic" Frogskins we've seen over the years are only a 4 base curve, what do you think @sOuLfUlFoRg
