In the posted video, you will notice that the downward slope into the helix has no trims.
Also, I remember reading somewhere - could be writings about building the Beast - that they ran it through its course before ANY trim brakes were installed and the designers who were riding at the time were scared out of their wits. I believe that is why the trims were added, at least the ones in the "shed". If I can find the article I was reading, I will post it. OR - maybe someone else knows where to locate it?
