Like the DLP Casey Jr. attraction YouTubed above, the concept art shows this as a ground coaster. In a sense Big Thunder Mountain is also a ground coaster, but it has lift hills disguised as real mountains. The draw of BTM is not so much the speed or thrills as the themed environment you experience as you travel. I'd be happy with a Dwarves coaster that has wide range of speeds to let you slow and experience your surrounding and then race you through the 'dangerous' places. Remember, thrills are not just physical, but also perceptual.
