Degree of polarization?

Not sure if anyone else does this, but I only rotate the filter the same direction as threading the filter on, it keeps me from un-threading the filter.

I've got to start doing it that way. Hope I can still rotate in with one finger.

I'm not particularly fond of them, but perhaps someone has tried a generic rubber lens hood for this sort of situation?

Pros:

• cheap
  
• can be cut to size
  
• can be folded back to access a CPL
  
• stores more easily than the Canon UWA flying saucers
  

• mounted onto the filter thread, so stacking a filter on top of it could cause vignetting
  
• not rigid, so less protection from impact
  
• next to the expensive OEM hoods used by your mates, they make you feel small and insignificant
  

When shooting at a wide angle, be careful not to over use the polarizer effect, otherwise part of the sky may end up a different colour than the rest. Here is an example of an over polarized effect on a wide angle:
