Hoya Green vs Blue vs Pro1

[Monkey]

I know the green boxed ones are considered a bit cheap and nasty, but apart from the pro1 being super slim, is there any other advantage over the blue box version.

If it matters im looking at the circ polarisers.

I also have a pro1 UV on as a lens protector, would i need to remove this or will i get away with them stacked.

Basically the Green box filters are uncoated, the Blue box ones single-coated and the HMC are multi-coated. There is also a Super HMC range which is err...more multi-coated.

cheers, will be ordering the kenko equivalent, just curious if the pro1 was needed. for the price i may as well get the HMC.
