Deane, one trick: Take Country Quickstep and slow it WAY down, to about 90-100 bpm. It fits many slow country shuffles.
Also, I made a great CW shuffle with walking bass, by simply changing sounds and drum kit in Big Band Fox style. I changed the last two sounds to guitar and steel, and the Trombones to piano. I changed the drum kit to RX Brush kit. Tempo around 120 bpm.
There are also some good CW styles in the Musikant styles and a lot of third-party conversions, including Kramer, which sounds suspiciously like the Ketron one. I'll look around and see what I can find to send you.
