RE: polarized sunglasses?
I have Maui Jim's they are excellent glasses, but pricy!!! The main reason I bought the Jims was b/c they had loads of option in Bronze coloured lense when I bought a few years back(my eyes get very tired wearing any grey or green lens type for extended periods). I have heard others say good things about the Bats(as you can see from the responses!) but never have tried them personally.
Be fore warned many glasses claim polarization but very few deliver in water peering ability like you want. You can't expect a pair of walmart specials to deliver any return in this department so be prepared to lay down min. of 100 smack on a pair of good polarized/water glasses. Maui's will run 150-300, I believe the bats will run 100 upto 250 range.
