The more you delay FS the better, but don't let IT expire.
Burn your runes with:
1. Frostscythe (if KM proc is active and you have this talent selected, otherwise Obliterate)
2. Obliterate (if there's no KM proc and 2+ runes)
3. Remorseless Winter (when there's only one idle rune)
4. Frostscythe (if there's no KM proc, one idle rune and RW on cd and you have this talent selected)
5. Howling Blast (when there's nothing else available, one idle rune and Frost Fever near expiration)
This is how I roll. I dunno if it's a 100% optimum but I don't have problems with IT uptime anymore.
