ya, it's sweet.. mine is sitting about three feet from my desk right now. i've had one with a vertical twisting drop (90 degrees) into a (reverse dive loop?), then it went through an inline twist and turned into the station. now i have one that drops vertically 180 degrees, goes up another hill, helixes down, then turns around into the station.
my only complaint with this set is it's lack of energy, it loses so much, the first hill after the lift can't even be like half the size of the lift. however,this is simply because of the scale of it, so all i can say is that K'Nex did a great job on it!
