I don't see why that a flyer would be have any less capacity than Mantis, I mean, the only diff between a normal coaster and a flying is that riders hop in backwards. The seats don't tilt back until the cars start climbing the hill. So if you were thinking they have to lay down to get in, they don't. I think a ride like Kumba would be nice, by the way. A flyer would work for me, though.
