I personally think a Wing Coaster is a better fit for SWO, while a mega/giga coaster is something that I think would fit BGT better. Unless they did a "Steel Eel"-type ride...an Intamin Mega-Lite or B&M Hollywood Dream (USJ) concept coaster. And yes, if they're going to do an Intamin along the lines of SkyCrush, PLEASE fix the restraints! That ride is brutal on the thighs even with the adjustments made to the restraints!
With that being said, the time has come for a major non-looping, airtime monster to arrive in the Florida market. I'm shocked Busch hasn't gone for it yet...I remember that's what the big rumors were pointing to in the build-up of Cheetah Hunt. I've also thought SeaWorld should do a hyper coaster themed to and named "Orca" for some time now. I envisioned it as a B&M having the "Cedar Fair-style" staggered trains and an Incredible Hulk-style launched lift hill. What a trip that would be! I originally thought it might be the perfect ride to put into San Diego, but then I found out about the insane limitations forced upon them by the California Coastal Commission and realized that a ride of that nature in SWSD would probably never happen. It's amazing the hoops they had to jump through just to get Manta west built!
