The one thing that Thorpe doesn't need more of is inversions.
Nemesis Inferno= 4
Swarm = 4 (or 5 if you count the incline loop like RCDB)
Total coaster inversions = 21 or 22
I believe Swarm 'officially' has 5; that's how it is marketed at least. Personally, I think classing the inclined loop as an inversion is a bit wooly, but y'know, little things...
The thing is, you look at Thorpe on paper and they have the second largest park wide inversion count in the world, only behind Six Flags Magic Mountain, which currently has 32. When you compare the sizes and the ages of the parks, it's pretty impressive. Now, we all know that loads of inversions doesn't make a good ride. However, imagine the marketability of 'the nation's thrill capital' if it had the most inversion in a park 'IN THE WORLD!!'. No matter what people say, it would work extremely well for the park to market themselves on a much bigger scale. And, to be honest, I think it's more than feasible for Thorpe to get to that record in the next, say, 10 years, as long as they head in the direction that they're going.
I'm not saying an air time filled coaster would be a bad thing; I'd love to see one, and I think there's a fair good chance of one of the next 2 coasters been such a coaster. However, I won't be surprised when we see another multi-looper make it's way to Thorpe some time soon...
