I was torn for the longest time, myself, on what chapter to play. I read alot of novels and had alot of different ideas for SM armies but I ultimately I started a Space Wolf army. I love their story line. It is established but it leaves alot of room for tinkering and individuality. Example: I only use Chaos models for my Wolves. I paint them up like the 13th Company and generally try and make them as scary looking as possible. I think that it is more fitting for the 40k universe, and the spirit of the army as Vikings to looks as dark, gothic, and frightening as I can make them. Ultimately it will come down to personal taste and what makes you happy. I hope you find a good army though, and please post pics and stories:victory:
