Yeah, that absoultely does. For some reason I have noticed that ride to have some pretty jarring roughness when the train is empty to half-empty. It's much better if you get the train at least 3/4 to full.
I feel the same about Hydra at Dorney Park. Several years ago, I got to ride it multiple times while there and noticed as the train filled up, the ride felt less rough. I know most people hate the ride, but I ended up really liking it.
Back to Infinity Falls, it does look like a fast, fun ride! It reminds me of Popeye & Bluto raftride at IOA. We were surprised at how speedy that ride was!
