Daedulus, if you want good smithing, which will increase your two hand damage and armor. Consider leveling enchanting/alchemy as well. Even if you don't use the 6-7 perks in each of these to make them truly shine, it's still amazingly helpful. For enchanting you have the fortify alchemy/smithing enchants. For alchemy, you have Fortify enchanting/smithing potions. See where I'm going?
I start by always having a fortify enchanting potion, then making the four fortify alchemy enchants on a ring, necklace, glove, hat/helm, usually out of grand souls from the Black Star, but any size obviously helps. Then when I have the 4 parts for alchemy enchancement I do the same for the smithing enchants, which are gloves, body, ring necklace. Then I go and upgrade the heck out of my gear. With smithing at 100 I can do some good upgrades, but with the enchanted gear to up my smithing and a super smithing potion, I can double, triple, or quadruple the stats on my gear.
Always take the increase to damage to your two hand and extra armor for heavy armor when you get the chance. I find that with two handed I only needed the 5 damage, the less stamina use for standing power attacks and the decapitation perks. And armor just the 5 extra armor, +25% for wearing all heavy armor and +25% for matched set were all the perks I needed to be a ultra powerful orc berserker. That and the smithing perks plus the alchemy and enchantment. I only needed about 28-30 perks so by level 31 you should be bloody well the most powerful thing in skyrim. Then you can spend the other 50 or so perks to explore whatever you want. I chose archery and am thinking maybe getting some extra fun perks like pickpockets xtra 100 carrying capacity.
