I disagree, Knotts needs a new show stopping coaster for the perfect version of Knotts. It's a Giga, + everything else yes, family focused. Another true Dark Ride, indoor family coaster, or Flying theater/Mad House, Family boomerang, more theming, shows.
You're right it doesn't need it, but if they do everything you guys (and me) wants PLUS a Giga/Large Hyper, Knotts becomes arguably the best "overall" theme park in the country and wouldn't need to add a thrill ride for 15+ years and they could solely focus on families and quality.
