That's fine as long as it doesn't cross the line to giving false information. As I said, I scorpioned on a flat cat track, which I was flat basing on because you need speed, as you said.
I'm not looking for tips on how to wrecklessly bomb a run on a flat base. From my perspective, I can't even safely get speed to make it up a flat section on a flat base, yet I see others not only doing that regularly, but also bombing. Which suggests to me that it's possible to do reliably without spilling. That's the reason for the question.
Its very hard to explain how its done, reading the terrain is key, you have to let it take you where it wants to and you have to know where its going to take you. You also have to be totally comfortable on your board and very loose with your body. Its not something that you can force yourself to learn but eventually it should come to you. I can flat base without even thinking about it these days.
