I love your idea's about Rush, especially the SRQ, But, if you look at reviews for Topple Towers, you will find that they are better to look at than to ride and are quite boring.Also, IMO , I don't see the appeal for a floorless coaster whatsoever. I am guessing most of you haven't ridden one of them and I can see why you would want one , but really unless your in the front row and stare down the whole ride, it's just a B&M version of Colossus. The same with Stand-ups, Looking at reviews for them , you can see the majority of them aren't great and that a much better addition could be made.Also, I think Depth Charge's time is up and has been for a few years now.
