This thread is so strange. People are replying to all kinds of questions other than biggest package against the ghost. It's interesting, but it is just off topic.
Anyway, my personal record is 21 racks in a row against the 9 ball ghost. It was on my home table (9 foot), fairly new fast/slidy cloth, balls opening up well. I kicked in two balls and was lucky to get this far, but played well too.
I don't know my record in 10 ball, but I once ran 21 out of 22 racks against the 10 ball ghost. This was on a tougher table. What can I say, I was dialed in. I was getting ready for a big match, and I played a guy where we took turns playing the ghost, I played 10 ball, he played 6 ball, races to 7. I won three sets in 22 at bats. It was pretty sick.
One of the amazing things about pool is how high runs stand out from ordinary play. Sometimes the stars just line up and you can do no wrong. That used to be what I lived for, now I like the struggle just as much. But it is fun when you touch something magic.
