CPL for Caribbean

[wizard13]

I know there are tons of threads out there about circular polarizers (CPL's) but most are discussing sky shots. I was wondering what CPL's you guys would recommend for the Caribbean? The sunsets and water shots would be the bulk of the shooting. Looking at Hoya and B&W seems to confuse me since there are so many choices. I know that I do not want to go cheap, I want one that will preserve image quality. The CPL will be used on the Tamron 17-50 f2.8, with a 67mm filter size.
Thanks for any help!!!

Sky is amazing in the Caribbean especially buttery clouds . A CPL will do magic there. I got Sigma EX CPL worked fine for me. But B+W and Hoya would be best.

B+W 67mm Kaesemann MRC CP. If you have two weeks to spare for delivery from overseas, www.maxsaver.net has good prices.
