That roll is great because its legit upside-down ejector air. I think it f*cks most people up as it actually feels like its trying dump you into the water. If you stand by it (or just watch some off-ride footage) every single train is filled with people screaming in terror/elation as it rips through that element. With just the lapbar, I'm sure its horrifying for some people lol.
Happy to hear the ride lived up to the hype for you.
