If You Could Bring 1 Halo 3/Reach Armor to Halo 5?

I’ve posted a similar question to the General Discussion Forum, but I want to see your guys thoughts here.

If you could bring one Halo 3 or Reach Helmet or Armor to Halo 5, what would it be?
P.S. - I mean exactly how the helmet is, not a new take on an old helmet rendered out of bubbles like some of the helmets (I’m lookin at you Decimator…)
I’d say I miss the Hazop helmet from Reach most. The halo 4 version was completely different and gross. At least Athlon is a little similar to it.

Please don’t cross post topics, thanks
