I'm currently using the Cinema Vivid series and they work great. Most of my shooting is around water (tropics) so I opted for the polarizers over regular ND filters. I've seen several videos that were shot with either just ND or stock UV filter and there's a lot of reflections off the water. With the PL ones, I can cut most of those reflections and the blues and underwater shadows really pop out and look 100% better. I usually try and frame it so that only about 1/4 to 1/3 of the composition is sky. Some days it's unavoidable and I need the shot with more sky but then I suffer a bit with uneven darkening of the sky but I can live with it. I just dress it up in post as best I could.
I will pick up the Cinema Shutter series when I get back to the mainland. So far, I've not missed the ND series in close to a year now but I do wish the Vivid series came with an ND32PL filter.
I did buy the black ring PolarPro ND32PL and to me, it was just wasted money. The colour cast was horrible. I'll try and do a side x side test pic when I get some down time.
If 90% of your shooting is over land, I'd say just get the Shutter series. If you do a bit of flying over water ie lakes or coastal, get the Vivid series. Or buy 'em both if you can afford to.
