Todd, Mantis is quite a bit smaller than Riddler's Revenge. IMO RR kicks Mantis' ***.
Does Flashback deserve all of these improvements? I would agree that they are needed to make it a better ride, but what is the point? When FB first came out, I think the novelty was the 4 across seating and the diving turns, right. Well, now B&M's are everywhere, so 4 across is no big deal. Diving turns are now outdone by diving loops, again by B&M. At least it will be able to be open in the summer.
Where did the rumors of an 8 inversion floorless come from? Sounds like wishfull thinking to me, unless I missed a press release or something.

Gotta ride 'em all!
