Best build for leveling a shaman?

I wonder what the best leveling spec for a leveling shaman is?
Any ideas?

I would say enhancement because from level 1-58 its very hard to get decent caster gear and ele runs quickly oom.
From 58-80 ele and enhancement are both good.

I always found elemental the easiest to level, really depends on your playstyle to be honest.
If you are good at kiting, then elemental. If you prefer to be a bit more tanky and not run around heaps then choose enhancement.
