I agree with the above. Perhaps though, you would be better off searching for people who were children when they saw the PT. It matters little what order you saw the films in if you saw all of them for the first time as a child, and they were able to merge inside your memory. I mean, seeing the PT films at 9, 12, and 15 (and the OT at 5), I definitely am able to separate them to a certain degree. But when you mention a Jedi, I'm more likely to envision someone from the PT as opposed to Ben, Luke, or old Yoda. When you mention a ship from Star Wars, I'm more likely to give an OT example, though with a few PT examples in reserve... just a though, if you're having a hard time finding contrasting opinions.
