I've only had their Dark Ale, so I'm not much help, but I'd start by contacting them. Most craft/smaller breweries can be really willing to share their recipes. Even if you can get the basics of a grain bill (types, but maybe not amounts) and hop varieties (and number of additions).
Just a WAG from what I see on their web site, I'd go with 2-row and enough Crystal 60 to get the color right, maybe hop to around 20-25 IBU ?
