Just go to Chicago and ride Whizzer. It's not exactly the same but the trip would be a lot cheaper and safer.
I think that once you ride Whizzer you'll find that these types of rides aren't as fun as you remember. At least that's what happened to me. A great ride for families though.
I disagree with you, that is much like saying "don't bother going to King's Island to ride Diamond Back, just go ride Raging Bull at SFGAM." While similar rides in that they are of similar construction and manufactures.
That being said, the only way I will be riding Zinger/Broca again is if I find myself on a whirlwind tour of South America for free, and with armed guards. Or if the park that now owns Zinger decides to build a bigger better X2.
