And that, my friends, proves that speed does not necessarily make a better coaster.
Pretty much the point I was making by bringing up Velocity. Speed doesn't define a good or bad ride. There are countless faster rides (which people have now pointed out) that aren't great but still faster than Icon. I genuinely believe that if people didn't know the speed beforehand, they'd probably guess it incorrectly anyway. As Ian's post signifies, perception is key. I could have sworn I was going about 90mph on some of my Taron night rides, but I know I wasn't. As long as it flows well, it makes no difference really.
Same for height. Speed and height are the same in that they don't dictate ride quality. I really want Icon to prove that much at least.
