its in teh top 3 launch coasters in the uk because there hardly is any. If you compare it against just coasters in the UK then it shouldn't appear on any top 50. Im willing to say the flying fish is better than rita. Its certainly more scary.
Don't quote me on this but I'm fairly confident there are only three launch coasters in the UK anyway (Rita, Stealth and Velocity). For my money though, it's the best one of the three. I understand your opinion on how it's inferior to other Intamin Accelerators but for me it does what is required.
However, at the risk of repeating myself over and over again, I'll never understand why it has OSTRs instead of lap-bars. Never.
Ya know, I think it'd be a loads better ride with lap bars. Certainly much more thrilling and it'd suit the airtime hills better. But, the general public like to feel safe and snug, I suppose
