Looking for someone running 4 DKs to share their macro system / setup. I'm only pulling ~7-8k DPS (Granted I'm in half Visc / Half blue PvP gear)

This is what I'm currently using:

"get diseases up" opener / refresher
/castsequence reset=combat plague strike, blood strike, howling blast, obliterate, howling blast, howling blast
/cast pillar of frost
HoW/RP dump
/castsequence reset=combat horn of winter, frost strike, frost strike, frost strike, frost strike, frost strike
I have obliterate on it's own key so I'm essentially going through "1" -> Opener "2" -> RP Dump -> "3" Obliterate

Can anyone show me their system or macros? I'm not looking for theory, I'm looking for tried and tested results.
