Dale Kirn used to go around the country demonstrating either a Thunderbird or Smoothie (the model is in the Stanzel museum, but my memory is not!) flying the stunt pattern on monoline. As said above, I was judging OTS at the 2000 VSC when Joe Kirn flew the OTS pattern with monoline. He did not do it badly. there have been various attempts to make a geared regular-type handle which would spin the wire, but I don't think any were really successful. I've seen one George Aldrich made.
