That would be the Sky Rocket II. As far as I know, Kennywood's Sky Rocket was the prototype (Sky Rocket I, if you want), followed by the improved SRII which has been a very successful off-the-shelf model for its size. Full Throttle at SFMM is considered a further evolution of the SRII concept, so it's sometimes known as a "Sky Rocket III". That moniker isn't used much, however, as there hasn't been much of a reason to. Maybe if the SWO coaster is somewhat like Full Throttle, even if not anywhere near a clone, we can call the coaster type an SRIII. But even so, "Premier launch coaster" would probably be easier for everyone.
