This will use the Ibox track.
Topper track is still considered to be a wooden coaster (Lightning Rod, Wildfire etc) whereas Ibox track is considered to be a hybrid coaster (Steel Vengeance, Twisted Colossus etc).
The fact that the renderings are in no limits mean that it looks as if it is a wooden coaster, but it will be an Ibox hybrid. At IAAPA Alan Schilke stated that RMC are moving away from the topper track towards the Ibox track as much as possible.
