Shaman leveling

Hey guys,

I've just started a fresh character on x1 Lordaeron realm. I really enjoy my shaman so far.
My question is, what is the most viable, if we can call it that, spec for leveling as a shaman?
Also, is it possible (in terms of efficiency) to play as a healing spec and do solo leveling?

Any general beginner tips that could prove helpful for someone who never played this class before are of value. :)

Enhance is pretty good for leveling. Ele is bad on lower level and becomes viable once u have sp gear from outland.

Leveling as Enhancement is by far the most efficient.
Even with Enhancement spec, and full Enhancement gear, you can heal dungeons all the way up to around level 50.
