I'd assume if Mack-Rides is doing a large scale coaster that's for UFW, it won't be a Blue Fire clone.
That said, it would be somewhat funny if this was them all along, and not Intamin.
I kind of assumed that after I read that news lol. Maybe something like a highly-themed Copperhead Strike would work wonders here. I don't see any way that this coaster is a Mack though.
