Altered Time - your #1 World of Warcraft Mage resource!

So I am starting to play with the No Ice Lance Build, and have a question regarding it.

When you get your proc to go = Glacial Spike into Instant Flurry. You get the WInter's Chill. Would you Ice Lance then with the 2 procs of FoF, or go straight back into Frostbolt?

I am getting very low DPS results for my item level. I have been trying to use wowanalyzer, but doesn't seem to be improving my results any.

Can anybody give me some tips?
