I am about to buy a new 67mm circular polariser & normally buy Hoyas. I dont really understand what the difference is between their green series, their pro 1 series & their new HD series, Except the big difference in price tags! Does anyone understand what difference different coatings make? or is it next to impossible to tell?

Different coatings. It does make a difference so I'm afraid the old chestnut ' buy the best you can afford' applies.
