This is actually far from their first VV coaster set with a spine. I actually got one of two sets for Christmas four years ago that included a spine called the Supernova Blast Coaster. I think that was one of their first sets they made that used a spine, and they've also made some afterwards where the flexi rods for the spine were permanently bent into specific shapes (I believe those are the grey rods that make up about half of the flexi rods in that set). I personally don't like the idea of using flexi rods that are permanently bent into shape since its almost like just using a weak piece of metal for your spine...
