This is quite normal given the fact that Sneak a hundred years as the master and the weight of the armor accordingly plays no role in a secretive mode.
So in the end I began to walk in heavy armor (Daedric). Of course, I've leveled Armorer to master repairing to 125% of the infinite one hammer, but still hovering so often for repairs just lazy. After a good distribution of the cuirass finally zero can break, this means that the armor level is falling. But the problem of light armor - break moment. Pumped to master a skill, the armor began giving half as much armor equal to Daedric, weighs nothing when worn (this is on expert). Started the game pumping light, walked of course in zacharovana glass (something found something enchanted with Sigil Stone). Well, about the armor options have already thrown great links, leaving only about beauty and functionality to talk.
