The Discmania FD1 is designed to sit between the popular Discmania FD and Discmania FD3. The Sky Walker II is the latest Signature Series disc for Team Discmania’s Casey White. This edition feels slightly closer to the FD2 of the past, but isn’t a direct clone. Expect a bit more glide and a slightly straighter flight. This is a great option to pair with the first Sky Walker FD1.
