The A5 is a new approach puck from Prodigy, which is a bit on the over-stable side of flight. It takes a good throw without turning over, but still connecting forward.
These Navigator A5 discs have a flat profile, so they are easy to throw even with the palm of your hand!
"All the slot discs in the store are described separately so that you can choose exactly the color or stamp disc that pleases you the most. This is especially good for Spectrum discs, where each disc is always different."
