Ok...I know that Steel Dragon is 8 ft. taller that Millennium Force, obviously is larger, but I don't think that's the fastest full circuit roller coaster. It's supposed that MF goes at 93mph at the bottom of the first hill while Steel Dragon runs at 95mph, that's a Guinness record, maybe someone could say that Steel dragon's first drop is a little bit taller than the first drop at MF by just 4 or 5 feet but...because of the cable lift hill MF train goes a lot faster that SD2000 train at the top of the hill, because this one uses a regular chain hill. If you see the "Making a Coaster" Discovery Channel show, you could clearly see that the train at SD2000 goes very slow and while its drops it takes like 5 or 6 seconds at the top of the lift hill and MF goes very fast even at the top, so with such a speed at the top is obvious that when the train hit the ground goes faster than the other one...so I think that it might be taller, but I don't think it's faster...
