My .02
Disclosure!
I've already received several PM's since I posted the below, requesting my own Zero-X Kicking and Banking system home-made booklet, but unfortunately I have no rights to distribute it in any way. I just highly recommend that for any systematic approach where math and assigned pocket values are involved, that you watch each phase/lesson and be ready to pause to take some screenshots and jot down useful notes, especially the rules. Thanks though!
I've purchased all Zero-X System video's available. Tor replied to my email just last week saying he's releasing a monster of a 4th video very soon. I love everything about the current ones. In fact, I've 'transcribed' his video lessons into a small bound manual full of his own graphics w/ all the zero-x rules to live by as taught. I'm probably not the only one to request a mini-book, pamplet, etc. so I took the liberty to make my own using MS Visio and SnagIT for screen captures.
I carry it in my case everytime I visit a pool room and it's saved my ass in sticky situations 10x over, including the most recent hill-hill battle I had in a local tourney that I ended up winning. My only complaint (if you could even call it one) is most of the scenarios are taught assuming the "zero" pocket is in the lower left from an ariel view. I had to design my manual to accomodate all the possible sides of the table you could be on. Then, I felt the "supercharge" of my game lol.
