DK spec for 4x ret + dk heroics?

[Myc]

I liked doing blood and going into frost enough to get icy talons so the pallys can rick roll with Aboms Might & Icy Talons
blood has decent healing, but for aggro idk how to build it up all that great on a DK.

[Prega]

today used a dk with my 4 retri pallys.
done a couple of heroics, without issues.
ofc he have great issues keeping aggro, expecially in aoe situations. his gear is somenthing i m working on.
my spec is blood. deep blood, with 8 pts in frost and 10 pts in unholy.
asap i will do dual spec, 2nd will be frost. atm cant use dual welding, weapons skills are too low.
