(pre) Game 4 - Grey knights

Later today I've got my fourth league game scheduled. My opponent is playing a Grey Knight list detailed below. Although he was only required to put 1500 points in his fixed list he opted to put his entire list. As a result, I already know what he will be playing and can plan my 600 points accordingly. Below are some of my observations and plans going into the game. Stay tuned for a post game report.
