Find best armor in oblivion

Normaly it is either glass(light) or Dedric(heavy)
But of you have the expations it will be fine amber amour(light) or fine madness amour(heavy) this does not include *special amour
Either way you'll want armor you enchant, it's better than anything you find. 100% Chameleon is probably the 'best' enchantment since it makes you effectively invincible but it also ruins the game by removing any challenge. I prefer damage reflect, spell reflect, spell absorbtion, damage absorbtion, fortify strength (boosts maximum carrying weight the most, better than feather), and fortify intelligence (more magicka = better spells).

You could also just enchant a set of clothes with nothing but "Shield" which ultimately yields about as much armor as a full set of glass or deadric but you don't have the bonus of having useful enchantments.
*special amour being the amour like holy crusader amour(which is more

To get the best armor simply go get all the bound armor spells. Once you have them go find a bandit or something and use them. Bring a hammer by the way. Let the bandit damage the armor. Then kill the bandit and repair the armor and drop it. wait til the time limit is gone and pick it back up and BOOM. You have weightless armor that is BEAST.
