At the moment kinda toying with the idea of starting a grey knight army, here's something I came up with, wasn't really sure what was best for termies equipment wise, I would very tempted just to give them force swords for the 4+ invul but I6 is just as tempting

as for the dread I was really stuck between taking a assault cannon (well Psycannon) or a twin linked autocannon, I was thinking of using the forgeworld model for it, anyways suggestions welcome!
