Yes, precisely why I suggest the strong skylight instead of
a polarizer. As you mentio, the polarization effect will be
variable relative to the wide range of incident light angles.

;^) it's science, and physics to boot - a genuine fact ;^)
I did discover that the skylight series do cause a very similar
deepening of blue sky when used on axis w/ the incident light,
whereas polarizers have maximum effect at a 90degree angle.
Some of my deepest blue skies have come from this combo and my
24mm f3.5 SuperTak. I suspect that the FishEye Tak's UV is more
accurately a skylight - the deepening (blue sky) it gives far
surpasses any UV filter I (used to) use.
... still need polarizers if reflection cancellation is what
you're after though. Read somewhere (and it also seems accurate)
that ~30degrees angle to the subject works best. Then adjust the
polarizer to cancel.
