Hmm then I'd venture it's all Light or nothing, as the perk says. :/ then again how many helmets are going to be "heavy" and still be decent to wear with "Light" gear anyways?

Edit: Example: Metal Helmet / Grimy Business Suit would look dumb. (in my opinion at least.)

totally agree with you .. looking at vault wiki now....13 armors....11 clothes....3 vault suits including armored one...13 headgear/helmets. i haven't separated them due to they don't say.

yeah, and if it turns out bad there's always mods.

also the list may or may not be incomplete

Oh I'm sure it's not finished, the perks aren't even up to date fully, haha.
