To add to above - I think Detty does it's job perfectly, very small footprint, high throughput, and packs a punch. I can't really see what else it can do? (Other than maybe have a second tower LOLZ). I've certainly seen worse "themed" drop towers than Detty, you leave her alone
Thanks for that picture of Zodiac - looks very different there, wow!
Forgive my ignorance but are there many other thrill flat rides that Thorpe could get to fill gaps in the park? I can understand their hesitance to do so with S&S problems (as much as I love Slammer & Rush)
