I'm not sure I agree anymore, Stealth they'll keep but Rita perhaps not.
I used to defend Rita, a lot, but now I think it's time to go. Funnily enough, after another visit to Phantasialand over the weekend, I found myself measuring the plot sizes of both Taron and Rita. Rita takes up more space than Taron, which really surprised me. Then I found myself thinking, what could Alton do with a proper Blitz like Taron? Taron (height wise) is only 30ft taller, packs 1:40 of ride time compared to Rita's 25 seconds and a fun filled layout like Taron's would easily fill the space AND fit the Dark Forest theme better (a PROPER escape the Dark Forest ride). They'd have to do something about the launches, Taron's is loud ("Es ist zu laut!! Est is zu laut! Die achterbahn ist zu laut!!"), there's no way the locals would accept that.
Anyway, this is me playing with crayons, and in no way reflects reality. I do believe Rita may have had its day though, perhaps she can be cannibalised for parts to keep Stealth going.
Otherwise, back in fantasy crayon land, Stealth gets the LSM swing launch spike treatment... I would be very much okay with that.
