Anyone know anything about these? http://www.durabird.com/ They don't seem to be available yet. It's a concept I often wondered about, treating a feather shuttle in some way to increase it's durability without degrading the flight characteristics.
There seems to be some connection between Durabird and Smashville Badminton club in Pennsylvania https://www.localgymsandfitness.com/SG/Singapore/2109962202379889/Durabird https://smashville.us/go/ https://www.facebook.com/durabird/
