Horizon FD3 Solar Flare Alden Harris Signature SeriesThe Discmania FD3 is the most overstable driver in the Originals lineup and this Signature Series entry certainly brings some stability. The Solar Flare is the Signature Series disc for Team Discmania's Alden Harris. This run has a bit more dome than what we typically see from the FD3 which should translate to a hint more glide, but also a little more stability too.
