Ultimately LW (dragonscale) provides better mail related armor for elem or enh.
Granted while Blacksmithing does provide some mail armors, the real gem you get from Blacksmithing is the weapons, which obviously Enh's spec's can use to a tee.
I went the skinning/LW route myself, which I was very pleased with. I don't like blacksmithing personally, as mining to me was a pain in the ***** as well as skilling up smithing seemed rather costly compared to LW.
