Ive recently taken a liking to heavy armor. Id like to work it in with my current character. Problem is shes very quick and nimble. If I take the conditioning perk in the heavy armor tree will it still be as though I'm wearing light armor, as far as being more light and quick?

Yep

Yes, it will be as if you're wearing light armour.

Thats cool to know. Ive always been the light armor type due to it being light and easier to manouver. I always found heavy armor to look very bulky on my characters but the appearance of ebony definately suits my current RP.
