the most gold im getting from blacksmithing is by making the rods for enchanters.  its actually funding my blacksmithing without me having to grind out ore too much

Mithril breastplate is low cost to make, sells for a couple gold, and rarely fails to auction first time out.

The adamantite set sells good too, although it is resource intensive.

Can't go wrong with phantom blade either.

I have to agree with you about the enchanter's rods, since it takes a fraction of time to make - you only need the ore and a type of grindng stone - quick, easy and sells fast in the AH - just don't flood the market with them.
