Im a Space Wolf player.

Ive been considering taking out my Lemun Russ Exterminator (since Im going to lose it soon anyway according to rumor) and replacing it with 2 Whirlwinds. I was just curious, is it worth it?

Seems like it might be nice, I can hide it in cover and just fire all day long, and using the Castellan missles means that no cover save is gained. I spent 208 points on the Lemun Russ, and would spend 170 on 2 Whirlwinds.

So I ask again... worth it?
