Only slide that I know had issues iirc was Punga Racers. Unless there’s a whole other thing I don’t know about.
But yeah. They could go with WhiteWaterWest too, they make similar rides.
Actually if they went with them. They could probably do some crazy things with the Mat Slide variety. They have a model called the Mat Blaster which no one has built in North America. So they could market that pretty amazingly
