George, In the mid-nineties, there was a stocky red- headed bloke on the pro-tour, who, for a while seemed to be winning everything --- driving myself silly trying to remember his name. Have seen him doing 'trick shots'.
Used to approach with a ball in each hand, and release one slightly behind the other, and the R/H ball would take out 9 and leave the 10 pin, which the L/H one would pick up. Also same basic shot with the 7 /10 spotted up, balls cross over and get each pin.
If you can remember name, I'll be able to sleep to-night.
