While a lot of manufacturers make very smooth rides (and very rough), there's always that one that sticks out in terms of smoothness (or roughness). So, that brings us to the question: What is the Smoothest ride from each manufacturer? Even if their smoothest ride is very rough, it can still apply to this question! B&M: Raptor, Cedar Point. While there may be a good amount of headbanging, the track is still very smooth. Gatekeeper, Diamondback, Banshee, and Rougarou have a noticeable rattle. Arrow: Gemini, Cedar Point. Non-wheel seats are butter smooth! Vekoma: Firehawk, Kings Island. Smooth, considering the track design. Intamin: Maverick, CP. I found MF to have a noticeable rattle. Premier: Tempesto, BGW: Smoother than the ones at KI, that's for sure. Wooden coasters in general: Since I haven't ridden more than one from any wooden manufacturer, I'd have to go with Mystic Timbers, Kings Island. Holy crap it's so smooth!
