I finally tried RnRC last December, and I am glad I did! I was more scared of the ride I had built up in my mind, even after watching you tube videos. When we got to the entrance, a CM could tell something was up, and he kindly explained the ride and told me it's only 90 seconds, just count back and it's over pretty quickly. He was right! I cannot ride it too often, but I will ride it. I find SM to be much rougher and jerky.
I must be in the minority as the take off doesn't bother me,,, I just sit back and try to relax.
