Bcg weight question

[Bigs28]

I've been researching all over online about whether a heavy or light bcg reduces recoil. I see every expert having their own opinion on the matter. So my build is

12" faxon barrel
Tbac ultra 7 suppressor
Superlative arms adjustable gas block
Jpscs h2 "this is what they advise for suppressed sbr"

Now my 2 bcg options
Cryptic coatings light weight bcg at 8.2oz or their regular bcg at 11.55oz.

Which do you think would reduce recoil?

I would do a light buffer with the gas turned down to just enough to cycle and a standard bolt.
