Thorns, I've got a couple of simple methods I was using a long time ago. They went ok but haven't paid them much heed. In these days of lots of meetings and available form they'd get a bit of action. Their big downfall was restricted action which led to a loss of interest.
I called them 'The Fresh Approach' and 'Ten Down'. Punters' Choice actually gave me a bit of a pat on the back for Fresh Approach for looking at a different angle. That was about 1985. Let me know how we can exchange material if you're interested.
