S&S's website states the 4D Free Spin is available in "Six-Element or Ten-Element Layout Options". A flyer exists for a "Standard Layout" and calls this the "S&S 4D Free Spin 110". The photo matches the model commonly seen at Six Flags parks. The "110" may be the height rounded up or perhaps related to the "Ten-Element Layout". No flyer or further information has been found on a smaller, presumably the "Six-Element Layout" to know the official name. Unofficially, rcdb is calling this the 106 until more is learned.
