Ok so I heard back from K2. So 07/08 is when the Gyrator was re-introduced with an extreme tip-to-tail rocker shape. They toned down the rocker the following year for 08/09. For the 09/10 season they went to the capped topsheet (rolled edges) with thinner sidewall, added harshmellow inserts for dampening. Not sure when they added the Flatline base shape, but I'm guessing either this season or last.
