Universal Orlando Resort (USO, IOA) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted October 2, 2017 And for sure they do not wish to carry the dubious honor of being the first park to scrap not one but two classic B&M inverts, right? Really, I think Universal needs the money to build whatever will be replacing Dueling Dragons. Why else would they scrap a functional B&M invert? Because if I'm not mistaken, behind Hulk, DD had one of the highest operating times of any B&M in the world? And with that much operating time comes a highly fatigued machine that was mostly only designed to operate for a certain lifetime.
