I was on a small river yesterday: shallow but fast running current, boulder bottom.

I tried 2 different shades of polarized glasses: greenish-black and brown. While they did cut glare, I could see a darn fish in that fast water or under the foam/ripples.

Meanwhile, one or two other fisherman were easily spotting fish as they walked up and down the bank. A friend (who was also wearing polarized glasses, different style/brand) even stood next to one of these fellows and could not see the fish that he had spotted.

I *think* but am not sure, that their lenses had more of a reddish tint (amber??) than my brown lenses.

I see from Cabelas that there are many different "brown" shades available: tan, amber, copper, etc. plus styles in photchromatic, glass, plastic, polycarbonate, etc. lense material. Any recommendations out there for shallow, fast, boulder strewn waters? Any thoughts/suggestions would be appreciated.
