That would work perfectly with OoF then. Now won't it. OoF has tons of space to build up on and plenty of room to add a very huge one, even bigger than HW's and it can be a terrain ride too.
I think the last major expansion of OoF was Paradise Falls, which was nice, big, wet, and very fun. A hydromagnetic rocket would certainly add some excitement to go to OoF and maybe reduce the wait times for Hurricane Falls some. I don't know what WoF budget is for adding new rides and I don't know how much one of those slides would cost them to build. I also do not know the 3 year plans for WoF if they have one ether and probably don't really care to know too much about it, it would ruin the surprise and the fun trying to figure it out.
Prowler was very fun to figure out.
