Two versions of the ride

I just rode it for the first time in March 2012. They now have two versions (not sure if they did before) a less intense and more intense version. I was with my dad who is getting up there in years so we went on the less intense version. I wanted to try the more intense version but we had only one day in the park and there were so many other things we wanted to do that we never went back. Someday I hope to go back and see what the more intense version is like cause the less intense version was kind of a letdown for me.
