Arcane/Frost Mage in need of help with Frost DPS

Hi, My mage is Icthelion Sargeras US - Armory Link -

I primarily run Arcane for single target fights with light movement, but have been attempting to use Frost for cleave/high movement fights and have had poor results.  After reading through the forums, I was able to analyze my own parses to learn if my FoF and Brain Freeze usage was acceptable (mostly it is not) but I am making strides which can be seen in my Twins log.

 

I used Frost in three of the 6 fights from the parse (Tectus, Blackenspore, & Twins).  It is twins I am most concerned about analyzing as it feels like an ideal fight for Frost and if i can improve my DPS there, I can pull it up on all fights.  On this particular twins fight I had 50 FoF procs/52 Ice lances and 31 BF procs/31 FFBs.  I lined up my CD's as best I could but still my DPS is much lower than my single target Arcane DPS.

 

Talents for each fight:

• Kargath - Arcane - SN-RoP-PC
• Butcher - Arcane - SN-RoP-PC
• Tectus - Frost - Nova - MI - PC
• Bracken - Frost - Nova - MI - PC  (Used flamethrower)
• Twins - Frost - Nova -MI - Ice Meteor (accidentally left this on from PvP)
• Ko'Ragh Arcane - SN-IF-PC

 

Any help you could provide would be greatly appreciated for either spec.  If I am unable to improve my DPS, I will have to go Fire (which i hate to do because I prefer Frost outside of the raid).

 

Thank you in advance for your time.  It does not go unappreciated.
