Frost Strike (exclusively) or FS & Death Coil?

Do you find its worth having Death Coil on most of the time?

I've got Frost Strike and Death Coil, in my Runic Power dump section.
With the FS key getting called twice as often.
And a toggle to disable DC entirely.

Most of the weekend I had DC off, as FS is a lot more damage for a Frost DK.
But DC is ranged, which can be nice.

What are your thoughts?

I heavily weight FS and keep one death coil so it continues to damage at distance with howling blast, but not cast so much in melee range.

Good for chasing down mages/hunters and everything that runs...

The only thing I toggle on and off is mind blast - everything else just GOES

Honestly for BGs it doesn't really matter.
