Martling, the side-by-side loop thing that you're talking about has been done on Texas Tornado at AstroWorld, and it is GREAT, especially with the 80 degree twisting spiral drop that precedes it! But my idea which has yet to be done is an element that I call the "twisted S curve". It looks like a normal S curve, until you examine it more closely, and then you realize that it has an inversion in it. You begin with a 180 degree turn that's banked at 90 degrees in the center, but on the exit path it keeps banking over to turn you upside down, instead of returning you to an upright position. Then you enter another 180 degree turn in the opposite direction, which is a mirror twin of the first 180 degree turn, so by the time you exit the element you're right side up again, and you've been turned upside down in the middle of the S curve. I don't know if it could actually be done, due to the strong lateral G's that it would produce, but what a ride it would be! I hope a new coaster gets one soon!
