CraigTCF, it is the park's decision, not Arrow's. I am sure Arrow would love to build a record breaking suspended. (breaking only their own record) If a park does not order one, it will never be built. The old arrow website had a section on suspended coasters, advertising them must mean they would be willing to build one. I agree, a 150' tall, 3500' long suspended would be awesome!
yitzhak1995, coaster designs are patented, but a patent cannot stop another coaster designer to come up with a new mechanism that does the same job. Look at inverteds, B&M, then Vekoma, now almost everyone has a fixed (not swinging) overhead track coaster, but all of them have a different way of doing it.

So you want a coaster in your backyard? I hope you have a big backyard.
