Essential accessories for P4P?

[roosta]

Just saying that the Polar Pro Shutter Collection is just ND only. No polarizer included with it.

I'll post my results in due course. The Vivid and Artisan PolarPro packs are the ones which are ND+PL... they are among those that are pretty highly rated. I have no doubt I will be annoyed at some stage using a a Sandmarc PL filter without having any ND grading on top, so I'll probably find the best ND filter rating based on the typical weather where I want to shoot video and then go out and get the polarized version of that ND with PolarPro or something, down the track.
