On the one at Gameworks, I ran into ball hangups on Hulk, often one per game.

Playing at the launch party last night in Chi-town, maybe one during the 6-10 games I played.

After playing the Pro some more, I find the Black Widow ramp isn't so bad. My shooting percentage on that was higher than the Hawkeye shot. After talking with George Gomez a bit, he said that the Black Widow ramp on the LE is even wider - the ramp piece is different.

Overall, as someone new to pinball (less than 1yr playing), its very tough. The shots are very tight. Makes AC/DC and Iron Man's shots look huge.
