All Hoya, Tiffen and B&W have slim polarisor. All of them are 5mm (not 3 mm)thick. I think Hoya should be good enough with cheepest price among the 3. An alternative choice is to buy a big polarisor say 82mm with a stepup ring.(in this case you don't have to buy the slim filter) But by some unknown reason the B&W slim filter is cheaper than their normal filters.

I agree the best way to go with wide angles is the step up ring approach. Even with the slim filters you muct try before you buy. If in doubt, borrow the filter at the store and shoot a roll of film of the staff at smallest aperture and most can process it on the spot. Check the corners carefully with a lupe. It helps if you shoot a light color or white wall.
I do own a Hoya 77mm Circular Polarizer / UV Haze Hoya Multi-Coated (HMC) Glass Filter - Ultra Thin (US$150) and a Cokin slim. No vignetting at all with either. But remember than to be thin, they don't have a front thread so you will need the slip-on or twist-in hood that came with the lens. I have heard about the: B+W 77mm Circular Polarizer Multi Resistant Coating (MRC) Glass Filter - Slim (US$180) but don't have it. And of course there are the Tiffens Although the step-up ring solution is a sound one, I did not choose it because of all my other 77mm lenses.

I also own the Hoya 5mm ultra thin polorizer and using it with a 20-35mm Tokina AT-X pro F/2.8 have had no problems. The UV ultra thin is 3mm thick. When I researched the ultra thin filters, I found that Tiffen does NOT multi-coat the ultra thin filtrs, while Hoya does.
