Scorpion at Busch Gardens has a rare element, a circular loop. It’s one of the few remaining. There was a great article in Vox about loops and the move away from circular to lessen g-forces. As a rider I can’t say I’ve found the loop overly intense, but there is only one and it isn’t that fast. Here’s how the park describes it:
The Scorpion® is one of only three roller coasters of its kind remaining in the world today, yet its sting is every bit as effective at instilling thrills through every twist and turn. Scorpion pulls you through a 360 degree loop and speeds of 50 miles per hour!

Go ride a classic if you get a chance!
