It's important to pop hard off the end of the rail. If you just spin but don't pop you won't go high enough to finish the rotation. Also make sure you look around over your shoulder to spot the landing and looking around helps keep the rotation going.
on a rail like that, you should be good. Just pretzel hard and whip hard. You will get it. I also found once I was starting to get closer, I would never accidentally just spin a 2. Once you got em, you got em. Practice makes perfect. Hope that helps
