As much as I want this to be a giga, I find it hard to believe SF is willing to spend that much on a single ride nowadays.
Unlike CF, in recent years SF has been very reluctant chain-wide to invest in a large scale, dynamic coaster (such as Goliath, or Superman at Darien Lake/New England, Kingda Ka, or Nitro at SFGA) for a park. Nothing on that scale has hit any Six Flags park in probably a good decade or two. And I mean from the ground up, so that doesn't count RMC conversions, as half that infrastructure was already present.
When SFMM announced Full Throttle, everyone was expecting something on par with Maverick--which was the breakout hit of the time--and once again, we were disappointed. I mean, FT is fine and fun for what it is, but to this day, it still seems like there was a real lost opportunity to do something lengthy with a large plot of land that basically has no other possible uses.
Again, I'd love a giga. But realistically, I'm expecting a more modest sized coaster with a gimmick/record of some kind. I've always thought that the West Coast could use something like Time Traveler or Ride to Happiness.
