Best Osmo Action 6 ND filter

[cobalt sequoia]

Looking to buy some ND filters to my osmo action 6. Will be doing some commercial fpv work in Sweden flying in a lot of different environments including sometimes over the ocean but mostly just normal grass, woods, dirt roads, fields and stuff. The whole difference between ND and PL and CPL kind of confuses me so any tips would be great.
Currently looking at:
https://www.telesinstore.com/products/filter-kits-cpl-nd8-16-32-for-action-6?variant=47466329866488
https://www.smallrig.com/global/ND-Filter-Kit-for-DJI-Osmo-Action-6.html
https://freewellgear.com/products/dji-osmo-action-6-nd-pl-filters
And the original dji nd filter although they are the most expensive.

I just run the tbs nd filters for everything, but that require a compatible tpu mount

I use frewell filters and they're pretty good.

I’ve heard good about freewell too. But I’m a bit unsure whether to get the standard day ones or bright day ones

Though the smallrig ones come with only 3 ND-filters but they add in a CPL filter so maybe it would be good to have that also

Usually I use ND16 or ND32 for video

Get the NDPL

They're pretty good

Talking about the bright day version of the freewell?

[last lichen]

Idk, I didn't buy the kit

So I'm not sure which filters each kit has

Yeah seems like Bright Day is what you want if it has PL

[cobalt sequoia]

From what I can see the standard day kit has nd-8, 16, 32 and 64 while the bright day has nd-pl

[cobalt sequoia]

Why would I want Pl?

Is it worse during cloudy days?

[last lichen]

If you fly near water or reflections

Otherwise regular is fine

But are there any downsizes
