Death Knight Tank/Level advice

[Redeyedjedi]

I've become very interested in playing a DeathKnight, had a blast in the DK Boot Camp start area. My Human Dk is level 59, and I would like to level her by tanking some instances in outlands. My question is, should I be specced more into Blood or Unholy? or if im completly off Frost. Currently I'm specced mostly into unholy, with a 5 points each in blood/frost to help out while tanking. maybe somebody could take a peek at it and give me some tips. I don't want to be THAT DK,
thanks for the help <3

Everyone has been "That DK" once in their lifetime of the game, I think its just one of the perks of the class :P

As a DK you shouldn't tank until level 65, I know it sounds dumb but that when you get your taunt and your 51-point talent.

Frost is the recommended spec to tank pre-80 dungeons since it has better dmg reduction than blood and improved AoE through Howling Blast and its procs.
