I think people are a bit confused about wheel space, all coasters have it to a certain extent and it is NOT what MAKES wooden coasters or any coasters rough, but it can possibly add to it. for wooden coasters, it is the hand carving of all the turns that make turns shaky, and the fact that the wood itself bends inbetween the ledgers making it "jackhammer." This can lead to wearing down the metal wheels over time and make it vibrate slighltly, but the roughness comes mostly from the deterioration of that track, so that it bends in between the ledgers when the train rides over it (usually through a valley), and the natural roughness that isn't painful, which comes from the hand making. For a steel coaster, it is just the bad shaping of the track, or the wearing of the polyurethane wheels making it vibrate. So the new texas giant, whether it has slighly loose wheels or (most likely from the pics of the wheel systems) not. As far as i know, it should basically feel like a steel coaster! And the guy from rocky mountain const. said nothing about it still being rough. He said keeping it from deteriorating, which is what MAKES it rough and hard to keep. See how it all ties together?
Btw hi im new here, and this ride will be insane.
