Leveling specs

So im leveling my mage and im loving it but im wondering what the best leveling spec is for a mage.
Frost because it sowers targets down.. And it gives great CC
x2 frost is the way to go for leveling, so many factors that slows the targets down, usually they will be dead before they get to you.
All 3 specs are great for leveling. I'd try them all and see what has the best feel for you. I personally love to level as Fire.
Currently leveling as arcane. the slow attached to Arcane Blast + ridiculous burst damage = everything DIES. I guess the only downside is the lack of bonuses to aoe, but thats a minor gripe when single targets die in under 5 seconds.
