To the op - perhaps it will help if you think of it as just straight rotation only with nine balls?
Took me a bit to get used to it, I play as an SL8, but struggle with the spots. A couple of hangars or badly played safeties generally are my downfall. Still have a lot of fun, and that is what it is about!
I guess it will just take a while for me to get use to it. I have only played 4 9-ball games.
