We got the same "problem" here at SFGAmerica. The (beloved) Whizzer always has a long line. Shockwave, Demon, Eagle, Bull... the whole bunch can be walk-on, but Whizzer always has a line. I've NEVER walked on the Whizzer.
I'm not a big fan of stand ups. But I do remember RRevenge being a great ride!!! Viper was much smoother than our Shockwave as well. I think by the time B&M did Revenge, they had all the kinds and jerks worked out. Maybe thats why it's so pop. It's big, but also re-rideable.
