Joystick is Rogue's "Pacman" yeast. It may well have started as an English strain, but it's mutated. I'm not sure whether it's from the way they cropped it or used it etc, but it eventually became a quick fermenting, highly attenuated strain. It's probably very "clean" in the ester department. If you have access to Imperial they have a couple that might be better for that style. Pub is Fullers yeast and House is Whitbread.
