On the Talos:
It's looking like a pretty nice Heavy Support choice: 8" move so it's not too slow. S6, T6, W7. 3+ save, with a 5++ for those nasty AP weapons and it also benefits from Power from Pain. Comes with 2 splinter cannons and 2 macro-scalpels standard, but you can replace those with all sorts of nasty shit (chain flails, liquifier guns, etc.). If I fielded Haemonculi I'd definitely take it.
