S&S does actually refer to “six element and ten element layout options available” in the ride brochure, so I think this is definitely a way that S&S distinguishes the two layouts.
Also, upon closer inspection, I actually think the Six Flags model/the 110 model may be the smaller, six element model. Because the standard layout that S&S shows in the brochure has an uncanny resemblance to the Six Flags models, and when you add together all of the listed elements in this model ( the “spin points” and “potential spin points”, excluding the brake run), then the layout shown has six elements in total. So I think Six Flags actually buys the smaller of the two models.
So if Adventureland is reportedly getting a “family” model, then maybe S&S has custom-designed them a smaller layout, or maybe they’re fitting less fins so that the cars don’t flip as much?
Out of interest, haven’t all of the Free Spins built so far apart from the one in China been the 110 model (so the Six Flags ones and Arashi, as well as the one Kings Dominion is building)?
