I love the SLC. Its a great ride, gets a decent turnover, is easy to load, has a high thrill factor and fits in a small footprint and has a lot of bang for the buck.
However, and I have noticed this: especially with Geauga Lakes Serial Thriller, is that after the first season, they changed the softer restraints (since they were being damaged) and replaced them with higher harder and more durable ones which hurt more.
So, I still love the ride, but hate the newer restraints.
