Unfortunely your armor rating of 738 isn't going to help you much.
And why heavy armor when sneaking?
I'm generaly in close range of hostiles, even though I'm an archer, so I use heavy armour because it's tougher. Besides I have the perk that reduces armour noise by 50%, my boots make me silent and improve sneaking by 43% and my sneaking skill is 100. Heavy armour or not, they only hear my arrow being released
