there's a tournament coming up at my LGS, hopeing to get some help its probably going to be mech heavy (2-3 ig player, 2-4 SM, 1 CSM, 1-2 eldar, 1 demon, 1 DE, 2 tau)

so onward:
haemy: wwp 85
TB x4 (2 splnter cannon, 2 blasters) 98
venom w/ splinter cannon 65

haemy: wwp 85
TB x4 (2 splnter cannon, 2 blasters) 98

haemy: wwp 85
TB x4 (2 splnter cannon, 2 blasters) 98

wyches x10 (hekatrix, agonizer, haywire, 2x hydra gaunlets) 170

wyches x10 (hekatrix, agonizer, haywire, 2x hydra gaunlets) 170

wyches x10 (hekatrix, agonizer, haywire, 2x hydra gaunlets) 170

talos (chain flails, TW haywire) 115

talos (chain flails, TW haywire) 115

talos (chain flails, TW haywire) 115

the total is 1599 so i need to lose 99 points, i was thinking of one of the heamys. or changing agonizers to venom blades

drop the splinter cannons from the tb... you're gonna want to fire the blasters every turn (more than likely) and the cannons are going to be a waste of points (found this out the hard way, personally). drop 1 TB from each venom and toss in a 3rd blaster in each boat. Remember venoms can fire both SC when moving 12, but TB inside can only fire when they move 6, If you dont have any mech to fire at, shoot the blasters at the biggest, scariest thing on the board for easy wounds/ID. Doing that leaves you at 1488pts. (edit: didn't add in haywire grenades to wych squads, so you would need to lose a homun as well)

Just as a thought, maybe (take one of your wych squads and trade it in for a 2 squads of 5 wracks w/liquifiers for objective sitting (but thats just me). (edit: this way would let you keep the extra homun)
