If you get the Kaenons and you want an all around lens, get the C-12 lens. That lens was recommended to me by Mike Long and he was right on, it's a great all around lens. I can't say I've worn every brand of sunglasses but I've worn quite a few and the Kaenons are very tough to beat. They're super light, non-fatiguing, scratch resistant, and above all the optics are just excellent for seeing fish underwater.
