Well the Call to Arms event has been announced here and now I have 1 month to decide on my pledge. I know it will be Imperium, but will it Adepta Sororitas (lots of stuff primed), Grey Knights (mainly Land Raiders left to build and some units to paint), or Raven Guard/ Raptors (Raptors have some paint so should be eliminated, but Raven guard is on the sprue.)

Really I am leaning to towards my Grey Knights as well they are the most painted of my armies plus I have 5 Land Raiders and a Storm Raven to build and paint, 1 Box Dreadnought, 1 MK4 Dreadnought, 5- 10 Paladins, 3 Dread Knights, 11 Purifers and few characters that are all primed., Plus a Thunderhawk in AI scale.
