I second that I use the Nap fletches & have no problems with flight
I always take a package with me when I hunt NY as the nearest shop is 30 miles away just boil water dunk the arrow in with the fletch for 10 seconds let dry for a few minutes & done
I will say they don't like the cold to much but I mean cold below freezing they seem to get brittle broke a couple hunting cold weather walking through the brush but still I don't go far without a package
I even repaired one in a convenience store while getting a morning coffee
