It's maddening coming up with an Ork list that I like, sucky Codices tend to have that problem :P
I'll be reworking my Ork list and hopefully I'll be able to put something worthwhile up.
As is, it's just variations of my battlewagon brigade, featuring:
4-5 Battlewagons full of Nobs, Meganobs, Shoota/Slugga Boyz, Lootas, or even Burnaz/Tankbustas
2 units of Lootas
rokkit/buzzsaw Koptaz and/or rokkit buggies
Big Gunz if I can swing it
Trukk boyz if I'm feeling lucky
I'll post up some actual lists later after I put more thought into it.
