"Sure it would be easier to ride with comfortable restraints, but I doubt ridership would increase enough to warrant the funds spent."
I agree. Revolution even with lap bars only would be more comfortable, and that's it. There are too many brakes on it now, and it would never match the rides in the late '70s. Very sad, too, because in its heyday, Revolution was quite a ride. Its layout is still good, but with the brakes, never again.
I'm going to have to look into this S:EFK thing on Six Flags' Facebook page...
