You can try the Carpenter Instructional Video. There is also some small bits about retrieves for pencils and chuggers in Legend 5 with Kozo Okubo.
Best is still to try to get someone to do a demo! Diagrams and descriptions would be very difficult.
Mark, I am very suprised that you mention Matsutani in that light. When I saw him on his DVD where his Stella flew off the handle and he was casting a rubber wind-up duck, I almost fell out of my chair laughing! His stickbaits, like the Atomic Pile, are controversial to say the least.
