The Shark plays differently in every house obviously, and even different from day-to-day, but in our PBAX league, the pattern started VERY tight but opened up a ton as the night went on. The higher rev guys had trouble with the backends flying, but us strokers were able to play the midlane read and not worry about the backends jumping. Basically the only two balls I used on it were a Cell (pin under the middle finger, around 5.5" from my PAP) with the MB in a strong position, and a Gravity Shift with the pin over ring, MB just barely right of the thumb. Both balls were sanded using Resurrection to around 800 grit CAMI (somewhere halfway between 1000 abralon and 2000 abralon) The key for me was to start in the track area, playing around the 12 board, going pretty direct up the boards. Once the shot started to break down, which it did quickly, I had to move left with my feet to keep the ball in fresh head oil, and get the ball to pick up in the midlane on the friction I was creating. As the night went on, I kept moving left with the Cell, then switched to the Gravity Shift for the last game one week. The final week on the Shark, it dried even quicker than the previous weeks, and I used a polished Spit Fire by the end of the 4th game and had a good look with it.
So the key is to create friction early on, then use it to your advantage as the night goes on.
