I rode Fahrenheit 2 weeks ago. The vertical lift is crazy! It feels like you 're going to fall backwards out of your seat as the train climbs. The drop is quick as is the rest of the ride. My favorite part of the ride is a small hill that gives incredible injector air time!
Fahrenheit is very smooth and does pack a lot into a relatively small area. The capacity is horrible as each train only carries 12 people. The day I was there only 2 of the 3 trains were running. We waited nearly 1 1/2 hours to ride on a day where the crowd was light. The station is very tiny and they do use assigned seating. Besides the gimmick of the vertical lift and inverted drop, its seems like most looping coasters out there. Overall I do like Stormrunner much better.
