I just got back from the airport, and 5 balls from my arsenal went through the x-ray machine: IQ Tour Nano, Tropical, Hy-Road Pearl, 100P, and a Street Fight. All of the cores showed up, and looked exactly like they do in illustrations/renderings, except one: the Street Fight. The core shape was nothing at all like what Storm shows it to be. In fact, it actually looked exactly like the Camber core of the Tropical.
Any guesses?
