Yep, the stall is much uglier than Ka's airtime hill. The supports on the airtime hill have much better spacing and the curve is a lot more satisfying to look at. The stall looks like something I'd build in Planet Coaster 2 because I'm not good with custom supports.
I'm not saying that it isn't necessary for ride forces or anything, but as somebody that loves to photograph coasters (the sheer amount of photos I've taken of Orion and Hyperia is embarrassing) I won't be taking many of that stall. Maybe it's better in person though.
