Games : Which smithing route is the best to get as all armor the fastest? (Skyrim)

I recently had to restart my account on the xbox 360. One way I went to get my armor the last time was smithing. I needed daedric armor so I took the right route when leveling up my smithing. I got the Dragonborn DLC shortly after I received my daedric armor. I made the dragon bone armor when I got it. I have the DLC now from the beginning but I don't know what path to take when upgrading. I have unlocked both dwarven and elven smithing now but I know I will run out of the perks to increase soon. Which path do I take left or right? My goal is to receive the dragon bone armor first and then unlock the rest that isn't unlocked.
