I use Saunders Arrow Mate NPV. Have been using it for years and won't switch unless they quit making it. The fletch stays on until you take it off. All of the arrows I've had that use the quick dry or epoxy type glues the bond gets brittle and eventually breaks down. A bigger problem when it get cold. The NPV bond stays flexible under all conditions and over time. It doesn't dry fast so it takes a while to fletch a bunch of arrows but it is worth it IMO.
