TBH I would drop BS for a gathering prof until you hit 70 get an epic flyer, and then retake BS and powerlevel it. You'll have loads more money at 70 that way.
As to your question though: I was Armorsmith all the way until a week ago. The reason: I picked up the S3 Chestpiece from Arenas and I plan to use it for tanking. So I switched to Weaponsmith in order to craft Blazefury. The BoP weapons available (epsecially with Nether and Vortexes on the AH) are just that good. Imagine dinging 70 and a few mins later you craft a weapon that is tier 6 quality. Tasty.
As to Armorsmithing, you could craft a tier 6 quality breastplate that isn't designed for tanking...and isn't fully designed for DPS either. Armorsmithing is really in need of a rework (which I read some blue posts that this is planned for WotLK).
Cheers!

Your ability to make money/farm mats, whether that be via gold from daily quests, or actual mining and farming, will go up exponentially with the epic flyer. With so many daily quests as well, it's easier than ever. Get that first, you won't regret it.
