Fire or Frost?Follow

I can't decide what build to go with forst or fire for a level 39 mage for PvP.

For fire i have this build http://www.worldofwarcraft.com/info/classes/mage/talents.html?2500500312202122300120005523201200023120000000000000000000000000000#none

For frost i have this http://www.worldofwarcraft.com/info/classes/mage/talents.html?2500500312202122300120005523201200023120000000000000000000000000000#none

Which one is better for PvP at level 39? Is there another build that i should do for PvP at 39?

Here is my character http://wow.allakhazam.com/profile.html?2534098

The way to think of it is.
Fire = Huge amounts of DPS in single shots. Low survival rate.
Forst = Medium amounts of DPS in a few shots. Higher survival rate.

Naturally. If you are going to solo a lot. Go Frost. You will live longer with shields and slowing the enemy down. Where as if you are a groupie, go Fire. That way they will ask you to come back for more because you will deal around 900+ on just a fireball attack at Level: 54. (Just an example).

With your fire tree, get Master of Elements and Improved Scorch. Playing with Fire and Firepower are great, but you'll get more out of MoE and IS.

Your fire build should have master of elements I think it is better then playing with fire in my opinion. Other that I think your build for fire is good.

As for frost build should put points in channeling frosts or elements precision it will help mana costs.
