Hello, first time poster here, but I've been reading since the beginning. So after almost 80 pages of posts I'd figured I'd chime in. One thing nobody has suggest yet (that I'm aware of) is a strata coaster, but have the traditional lift. Not sure if a chain would work but the cable lift would. Imagine a 400ft Millennium force or i305 or even something better. I wouldn't really care if it was B&M or intamin just as long as its a good ride. As far as the b&m invert goes, I've thought of that as the most realistic option from the start. If its one of those, hopefully it will be the tallest and fastest.
