I also do not think there will be any airtime, the hills just look like they go up or down and into a corner. You might get a tiny bit of ejector but I dont think so.
Neal you will remember the one in Bakken, the hills looked like this and how much airtime did we get? It all depends what trains they fit though, the ones in Bakken tended to kill the speed up the hills quite a bit.
I am not let down though, Alton always said it was a family coaster and for the UK this is a good addition. It could have been a lot worse.
