I might be an odd example, but I use my Wicked Siege (2000 abralon) on just about everything. I used it on Beijing taking most of my hand out of the ball and feeding it up the gutter. Because the ball is so clean through the front part of the lane and doesn't react hard to the dry, it's a great short oil ball for me, but I'm starting to really like the gutter shot if it's there. I also used the Wicked Siege on Tokyo, starting at 6/7 at the arrows one night and 12/13 the other, obviously putting my normal hand in the ball.
I haven't matched up to Atlanta all that well. The first night I started with urethane (Slate Blue Gargoyle) up 5, but switched to the Wicked Siege targeting 17 with a decent belly after the outside went away. The other night I played outside with a Nuts Pearl (1500 polish), mostly because it was new and I didn't have anything dramatically better in practice. Atlanta has lots of friction, so keep your options open.
Mexico City I used my Black Widow Bite both nights. The other short patterns (Stockholm and Sydney) I used either the Wicked Siege or my XXXL. Other than that, I pretty much used the Wicked Siege for everything.
