i use the stromraven in the stormwing formation..and i run it basically the same in both the ravenwing and ultramarine lists.
the first thing you need to decide is the role its going to take as thatk will determine the weapons and the point you want to throw into it.
to me the standard configuration with MM and AC does more than enough..but im using it more for anti air.
with the Ravenwing i throw on the sponsons but i find combined with the banner of devastation its total over kill.
it works reaaly great with assault squad or terminators..if you want a cheesy thing to do purchase the sky shield landing pad..i cant give the points that way the storm raven can be on the table T1 so you assaulting turn2 haha
