Suppose you get to 100 Smithing, and perk out the Heavy side of the tree. You take the Dragon Armor perk.

Can you now craft both Dragonplate and Dragonscale armor, or just plate?

I'd like to make a character who crafts heavy weapons but wears light armor. So I wouldn't be taking any light armor crafting perks, but I'd like to wear dragonscale.

Both.
