I don't understand what TWC means, are you saying Twin Wolf Claws or Thunderwolf Calvary. The former I will most likely take at somepoint down the road, the latter... never... never ever lol, not even if I played straight space wolves.
This is the basic load out I was configuring in my head for "counts as" IW:
-frost blade, belt of russ, wolf tail, melta bombs, pistol, runic armour, saga of the bear
- not sure how I want to configure him yet
Also I'm pretty sure I want to get a Dread in here, cause I have an awesome forgeworld one
2x 10 Grey Hunters in Rhinos with meltas and power weapon
1x 10 Grey Hunters in Rhino with Plasma and power weapon
1x 12 Blood Claws with power weapon
only thing that stands out to me here are the actual Wolf Wolves, I know there is some sort of mutant laborer conversion there just ready to happen
Land Raider Redeemer (Warpfire Cannons) w/ extra armour, multi-melta
5x Long Fangs w/ 4 missile launchers
Also considering putting several units in subterranean assault vehicles (counts as drop pods) which would be epic to model!
