What lens are you using? I only have one lens that uses the filter threads for the lens hood, and that is because the lens didn't come with a hood. If you have a hood specifically made for your lens, it shouldn't use the filter threads.

I have a B*W "slim" polarizer and I love it.

Like Another View suggested, I would get one in 77mm, that way you're covered if you get a lens with a larger filter thread in the future.
