I think I have settled on my kill team list with 5 Rangers, 4 Scorpions and 1 Exarch with Biting Blade and Stealth Move Through Cover. Not sure if the Scorpions get the benefit of the Exarch power in kill teams but I had points left over for it. I figure this will be a good start on my stealth Alaitoc list. So the plan is to have the above 10 models painted as best I can by Jan 1, 2011. I think that is a reasonable deadline.
