Just a follow up
Seems as though the Fletch Tite does the trick for me. When I have an errand shot or I hit the area of the target that is shot out it used to just pop the feather off, actually I could just softly push against the feather and it used to pop off.
Now I haven't had any feathers "pop" off but this morning I had an errand shot and it had a glancing blow to the feather. The base of the feather stayed attached to the shaft but the feather barbules were striped from their base with that white feather base still attached to the shaft.
So I am now a fan of Fletch tite, Thanks for the help guys/gals.
On edit; My routine is just clean with acetone, no sanding, apply Fletch tite, spread it with a tooth pick and apply it to the shaft... Wait 5 mins. in clamp, put it in the rack for 48 hours.
