Just search for the blend you're interested in and they typically have at least a few reviews.
Just pick a few things and try them out, just like cigars, everyone has their own preferences. Personally I don't mind latakia blends, but I know a few guys who just can't stand latakia in anything. Pipe tobacco isn't very strong comparatively to cigars. I've only ever felt a nic kick from one pipe tobacco of all the blends I've tried.
Oh and, an english just refers to a tobacco with no flavoring/sweeteners added. Theres two types of pipe tobaccos, englishes and aromatics.
