The Cypress was originally launched as an overstable distance driver that had flight numbers of 12/4/0/3 but has since been retooled to be a more friendly disc to players of all skill levels. The retooled Cypress has flight numbers of 12/5/-2/2 and has a slightly more blunt rim edge. Make sure to note whether you are buying a first run or a production run, because those two are quite different from each other.
