Here's my build so far at level 37 (skyrimcalculator(dot)com/#102506). Sorry they don't let me post links
Current Skill Levels:
100 Smithing
100 Speech
100 Sneak
81 Archery
80 Conjuration
50 Enchanting
37 Light Armor
35 One Handed
Most of the time i can just one to two shot sneak snipe enemies with my bound bow. It's pretty awesome. I know the bound bow is nowhere near as powerful as the some of the created ones but not having to worry about arrows is just plain awesome.
My question now is where do I invest in points? I leveled up smithing just in case and I can get enchanting up as well but I don't know what to do with it! Can I use smithing to upgrade my ancient armor set? seems like its just a minor bump in armor. So would love some archer smithing enchanting tips! =)[/color]
]Should I put more perk points into light armor? the tree seems pretty sweet. I really only die when I get lazy with dragons but always nice to have some more defense.[/color]
Any perks I'm missing?
Lastly, as I said, I usually just cruise through dungeons sneaking and sniping but sometimes I'll bring out the summonded Daedra to help smush or tank for me. Is that better than having two atronachs?
thanks all...appreciate the time!!

As for Smithing: you can definitely put some more damage on bows if you get the perks or level Alchemy and Enchanting.
