The Double Chocolate Stout is a good beer, but I personally can't drink something that sweet for long. Young's makes a great Oatmeal Stout that I enjoy. You might also check out Murphy's Stout. I enjoy that as well.

I used to live just north of the Stone Brewery in San Marcos, CA. I went down for a tour last summer. I've tried them all, but probably most enjoy their Smoked Porter. I also enjoy their Ruination. As far as the Arrogant Bastard - it's definitely a love/hate kind of beer. They also make a Double Bastard, at something like 10+% AC. I do agree about the Stone beer line - while tasty beers, they are very strong. It's best to be where you're going to be when partaking.
