Which is the better Circular Polarizing Filter?

The Hoya PRO 1D or Hoya S-HMC Circular Polarizing SUPER THIN filter?
For my Canon 10-22mm lens for landscape photography?
thanks, George
I have a Canon 40D
I don’t know the pro 1D how many layers of coating has, the other one has 12 layers of Super Multicoating, so my question is which is a better quality?

IMO the Thin mount since vignetting can be a problem with ultra-wide angles lenses like your 10-22mm with a standard thicker mount.
