Azerite Trait Help

I just got my 385 azerite head piece from my M+ cache. Now I’m evaluating all of my azerite traits.

I’ve been comparing the traits online, but I was hoping to recruit some advice on new traits I should pick, or if my new helm is worthless. I do enjoy raiding, and I’ve been getting into M+'s a bit.

Current set up is in the armory. New helm is a 385 High Altitude Turban.

I’ll have to swap my chest piece to have my Archive of Titans now. Both my new helm and shoulders have access to Overwhelming Power. Do they stack in any way, or is only worth it to take one Overwhelming Power? Or would I be better off taking 1 overwhelming and 1 unstable flames?

Also, by taking archive on my chest, I lose Shrouded Suffocation. I’ve enjoyed having those extra combo points, but is it all that amazing? I’m essentially swapping my Shrouded Suffocation for Double Dose, which, sims higher according to WoWhead. Thoughts on Shrouded?

Thanks for any help!
