In conjunction with Sussex, I'd recommend POW (6 or 7 ales when I chanced upon it mid 2011), and try to do Bull on a dry day, also taking in the Cock in Luddesdown, a couple of stops along. With good ground both are pleasantly walkable, vaguely cross country, (google satellite will show you) from Farningham Rd and Sole St stations on the same line. A fine Cock & Bull tour!
