Champagne flights can be used with the Champagne Rings for a secure fit on any type of nylon or poly shaft.(Sold separately). When Champagne flights are used with the Champagne Rings and pushed onto the shaft, the Champagne Ring goes over the top of the Nylon or Poly shaft preventing hard deflections by another dart hitting the back of your shafts.
Champagne flights can ONLY be used with Nylon or poly shafts.
A-Z Darts is the high-end of customer service. The flights are working great. I recommend anyone considering them to give them a try.
