Yeah, I emailed Joe Tucker awhile back, inquiring if/when another racking secrets would come out. I had mentioned to him a few things I learned. I can't recall, but I think he had some additions, but not ready to put a second edition out, yet.
One thing I mentioned, that I learned in Japan at a place called Flannel (Nishi-Takashi-Madaira, Japan.....where pro player, Naoyuki Oi, is sponsored)....is if you have a perfect 9 ball rack (all balls frozen to each other, and rack placed perfect without any tilt), then break 1 ball width from the side rail at the head string. Aim straight at the head ball (1ball) and hit is perfectly straight (stop shot or a little draw back).
I was able to pocket the wing ball 15 times in a row on the break.
