I had this banks drill on my practice shots page that I completed a couple of times when I first invented it.
Now I've spent the last week trying to get the damn thing on tape and I can't get past four balls.
So I've given up on the long version of the drill. My new, more reasonable goal, is to set up the table with any four of the eight balls and bank those in.
Much easier, but I still haven't got anything taped yet.
