The sequel will be "Deflecting Reflections" -- about how use side spin on kick shots.
As for the marketing stuff.... Several times I hung out a little at a vendor's booth at various expos and tournaments. They were selling low-squirt shafts and had a table to demonstrate them on. The had a few different models and I think joint variations so customers could try them out. I must have watched ten or so customers in total try the shafts.
None of the customers ever used side spin. They had no idea what the shafts were about. Maybe they never used side spin in their normal play so why would they try it in a demo?
Some of them bought shafts then and there.
The bottom line for me from that: The vast majority of pool players are unaware of the vast majority of the game, whether that's about the details of shots, the rules, the history, or the players. For better or worse, that's who you have to market to because that is by far the largest part of the market.
As for the low-squirt stuff.... I've used a low-squirt (AKA deflection) shaft since about 1980. I liked it because it hit the ball straighter. The cause of squirt was not widely understood until about 1998 but even before that understanding it was clear to me that less was better.
