I have recently picked up Cooper too, I've played 3 games with using one of everything you get in those boxes (except 3 Runaways)and no upgrades to get a feel of what the different models can do. They are a lot less static then I thought before playing a game. The dogs add a lot of movement tricks and the rex has a good bonus push when you dont need to give things crows. The Runaways are very cool models as I see the things they can pull off. I'm only 3 games in but I'm already seeing the layers this crew can bring.
