Initially I was in the 'same number of wounds for 1/2 VPs so why bother' camp on the Carnifex +1 wound option. Experience has taught me otherwise. Carnifexes often have to leave cover - that 36"range has its limits - and even in cover a 5+ just isn't that great when lascannons wound you on a 2+.
If you are throwing 170 points into something anyway, then 15 to give itan extra wound is a bargain.
I'm not sure why a spinegaunt is preferable to a termagant. S4 can hurt speeders, so terms can at least protect a flank. Then again, I'm not sure what use masses of 5-6 point gaunts are end of story. I prefer hormies and that may explain my preference for defensive S4 shooters
