It does if you're talking about lessening the sustained airtime. Just look at Kingda Ka's speed hill that has brakes on it.
Yup, and I think YOLOcoaster's Top Hat is going to be exactly the same as Kingda Ka's or Goliath's "Airtime hill".
I remember seeing it's air time listed as around 1.25. But don't quote me on that. The loop is at listed as 160 ft. That's loop size not just the height of a loop off the ground. So even though some loops are higher off the ground. They are just loops that have a higher starting point off the ground, like Viper.
