It’s not as simple the synthetic feathers feel completely different. I’ve played with the NCS Pro on a lot of different occasions but 90% of the time the shuttles are too slow during drives and drops. Plus most of the feathers are taken from goose/duck being eaten, that’s why they’re so expensive now because of a drop in demand for the birds.The use of synthetic shuttles is way overdue. The cruel practice of extracting feathers from birds is barbaric. It's not beyond science to create a suitable shuttle, even if they would break after a game or two. I have introduced newly manufactured shuttles like Bird 2, Bird 3 and Apacs to three clubs over the past 8 years and overall it's been about 50/50 willingness to accept them. People generally don't like change but they should see it as an opportunity.
