I have the 24 also. It is incredible!
My hood will fit over the B+W filters but I have to wiggle it around 
quite a bit and kind of force it over to its proper mounting place. 
Did your hood cause the vignetting because it was too far forward?

With one filter I have not had any problem. When I stack 2 filters then I 
get noticeable fall off in the corners (which can be nice if you want it)

It may just be the filter/sky interaction - or - did it vignette in the 
lower corners also? If its just in the upper corners its the former. I 
get the same thing with the atmosphere here at 600 ft. elevation. No 
filter effect around the horizon and lots of effect up in the blue sky. 
This exaggerates the ever so slight dark corners of the lens that do not 
show up except in this kind of situation. You can see this also by 
shooting a completely even colored and evenly lit wall - you'll see it 
then but not in normal picture taking. I simply consider it a "pre-edge 
burned" effect. I think lots (all) of lenses do this. We just don't see 
it in day to day photography.

I say its time to test your set-up so you can correct it.
