If you saw the Etonic Edge footwork thing they filmed on Robert Smith during practice, he was standing much further right and playing pretty direct up the 12 board area during practice. The Shark pattern is long, but there's not a ton of oil on the heads, meaning you have to start moving left to find some head oil to push it down the lane while still getting through the carrydown at the back. Combine that with a high friction surface and a ton of bowling on the TV pair and you're going to have to start moving left a lot.
