Big fan of the style, and I enjoy both of those! Brooklyn makes a killer one, SA is always worth drinking, and I really like 2 Roads'. Its a very low flying style, so its nice when theres decent examples. In the same family (sort of), rauchbier: JA smoke & dagger is the tits.
It's fantastic, IMO. One of my favorites actually (outside of the great German ones...Hacker, Paulaner, Ayinger, etc.)
