Ever since Oblivion have been a heavy armor man. I am a firm believer that you need a good defense to crush a good offense. But after listening to this weeks podcast every seems to have ditched heavy and moved to light. I am most likley going to stick with heavy but I was curious on what other people were using.

Light armour, because it looks better!
I'm always a huge fan of martial skill winning over being a walking piece of metal, so I just roll light armor and dual wield.

If my fists weren't made of metal how would I punch bears.

Had only a robe and a mix of light/heavy at first but I'm going heavy armor all the way now. 

Heavy because my character is a tank.

Naked.

No Armor. Stoneflesh, however, now gives me 120 points towards armor.

Light now, i like the ability to sneak sometimes, heavy makes it more difficult.

Heavy armor LIKE A MAN.

Light armor, since I'm playing as a rogue/mage/thief.

My second character build is a Nord using Heavy Armor. Using just a sword and shield, I've been able to handle every encounter save for my first troll run-in and another with a dragon/dragon priest combo.

Also, I remember them saying they dumped Heavy Armor b/c they found themselves sneaking. On my first pure-Wizard build, I unintentionally leveled up Sneak a lot, due to my habit of clicking in the left stick in hostile areas in Bethesda games, but my Nordman rolls hard. Fuck Sneak.

Light for sneaky sneaks, but considering I seem to die if anybody gets close to me anyway, I'm thinking about just wearing robes or some fancy clothes. Mostly I want a hat with a feather in it, but I haven't found one yet :(

I use heavy Orcish armor on my lvl 17 Orc. I prefer being a buffed tank to a sneaking stabber, just my playing style.

Both.

Heavy, like a boss

Heavy. I run up to dragons and slaughter them with my hammer.

My Argonian Berserker will smash you with his Dual Wielding while wearing 400 pounds of STEEL!

Light Armor, I don't need heavy armor to bust people's asses with my Greatsword.

If I can make the armor rating go over 400, you damn well know I'm going to. Mainly because dodging isn't really viable or cool in these games. Otherwise I prefer the thought of skill over tech.

I'm a sneaky archer, so I'm light.

I'm going with mage's robes. I'm not sure if that counts as light armor or if it's just the boots and gloves I have on that is causing the skill to go up.

Light. Usually go all out heavy armor/power armor in these games, and maybe some magic, with a fat ass big weapon or sword and shield. But I considered how much I liked being a khaijit thief in Morrowind, so now I roll around as a argonian thief/assassin. Daggers for backstab, dual wield mace + sword for straight up fights, and bow for anything weak/range/dragons. I rarely get detected now so. With 100/100 smithing I still have about 250 armor as well in my quest reward (dont wanna spoil) armor.

Heavy, because my dude needs it!

Both, heavy armor boots and gauntlets, light armor up top, I think I am only wearing a robe that gives a magic boost.

I prefer light armor since I'm a stealthy type. With enchanted glass armor and some light armor perks beefing it up, I seem to soak up a ton of non-magical damage just fine.

Light armor because sneaking is cool.

I use an armor blend. Usually, I protect my chest with heavy armor, then use light armor with magic bonuses over the rest of my body. To be honest, I prefer light armor because it looksso much cooler. A hood is way more stylish than a helmet.

Only just started this but trying to go for a rouge/thief/assassin build with a little magic thrown in. So light armour all the way with plenty of stamina to run like hell when I need to.

Thieves always wear leather.

Heavy, I'm basically playing the standard Nord Dovahkiin warrior from all the promotional video. Planning on going back in with an Assassin/Ranger character later with Light.

This tasty ass light armour, come at me, bro. Oh wait, I killed you from the shadows with x30 dual dagger stealth damage. Sorry man.

Light Armor. The perks are awesome.

Heavy Armor.

Heavy Armor looks better than the light armor in this game, plus when you go smithing you have to pick a direction and I want daedric weapons.

I wear a robe and then light elven boots/gauntlets/helmet because I play a rogue mage. Next playthrough I'll be a full on warrior and wear heavy armor, though.

Heavy.  The stamina hit isn't that bad when you consider the fact that your armor rating is about double that of light armor.

Those light hoods look weird on my nord. It makes his head look too big compared to the tight cloth on the rest of his body. Plus, I have some pretty fucking cool-looking heavy armor pieces.

Heavy. I like to walk in and destroy everything while looking into it's eyes.

I'm with @LordXavierBritish. Punch those fuckers with fists of steel!

If you spec out heavy out you can become a walking tank, with double the armour rating plus whatever bonus perks you have unlocked, add to that having the ability to make heavy armour weigh nothing.

light, playing thief/assassin heavy armor makes too much noise.

I either use light or nothing. So much classier and so much better looking.

Light, but my main character has always been a fast-moving, hard-hitter. Its a little risky, but I like to get in close fast, smash the foe with brute force, and work on evading rather than full-tanking. My barbarian has to be nimble, even at the expense of survivability, and I like that playstyle a great deal.

I'm wearing a set of fully upgraded scale armor at level 30 and it is going well. I could wear glass, but the scale armor looks so much better on my guy.

I'll probably try a heavy armor sword'n'board character to see what that is like later.

Light, I like bein speedy. Plus oakflesh and stoneflesh are great for jacking up your armor rating.

Light armor because it allows me to sneak up behind men easier. To kill them of course.

I'm using heavy armor because that's seems to be all I find. Granted, I'm focusing on the main quest. I've sunk enough perks into heavy armor now that it's probably too late to switch to light.

Light armor, my arch-mage rodes gives me all the magicka regen. shooting spells all day everyday.

Grab the Jagged Crown on the Stormcloak quest and never turn it in. Decent heavy armour rating and it looks badass.

My Breton Battle-Mage is running a heavy Armor. I have been thinking about maybe changing to medium or light, to be able to carry more loot.

Heavy armor with sword and shield. Come at me bro!

Heavy all day. I have no interest in moving around. I just like to plant my feet in the center of a room and then hit things until they stop moving and I can take all of their nice things.
