Just my 0.02c.

That sounds very resonable, just one question: does it not interfere with the lens hood?

Be prepared for eye-popping prices. But, doesn't get any better, ever.
Well, they certainly are great filters, but they way off my budget
I use Heliopan slim version filters. They are optically and mechanically excellent. And as others said always buy 77mm size CP and use step rings to mount it on other thread size lenses.
The Circ. Polarizer is used for effects/sky/reflections/... and the UV-filter only to protect my 17-40 in sandy/dusty conditions. The 17-40 needs it to be weather-sealed (although my body isn't), so if you're at or near beaches, it is strongly recommended (supposing you'll get the 17-40 one day ).
Yes, the 77 on a smaller diameter lens will interfere with using the lens hood. But I've never really found it useful to have the lens hood on a circular--how would you turn it with the hood in the way??
I use a hat or such to shade in front lit situations but then I almost always shoot with a tripod.

Dunno, just thought, maybe you set the circular and put on the hood afterwards
However, guess I'll go with 77mm and step down ring then.... 'cause I think Bart is assuming right Bart wrote:

Avoid the new Nikon slim polarizers II; I have it and it is as difficult to clean as the Hoyas. I *suspect* it may have been manufactured by Hoya even, since the multicoating color looks similar.
sorry to bring that topic up again.... at least i've made decision about the brand B+W
now the next question: is it worth the diffrence of price to get the slim versions of the respective filter, if one plans to use them also on wide angle lenses? (without CF, since I'm still on slides.... yes, I am )
The slim filters are very nice, and I prefer them. But they ARE more than the regular ones, and the optical quality is the same. I don't think you will have vignetting problems with your 20mm lens.
I avoid the slim polarizers. They were created to avoid vignetting, and with the crop factor that is not an issue. Another reason to avoid them is that they don't have a filter thread on the front. Now I'm not looking to put more filters in front of the polarizers, but that means you can't use the snap-on lens cap. No problem, they say, we'll give you a slip-on lens cap. But B+W gives you a plastic slip-on cap, and on a warm day it will easily fall off. Try replacing a 77mm slip-on lens cap - not easy.
