I started using tape last year. My feathers were not quite seated on the shaft after application. I press the quill down with my thumb also. Gentle pressure, nothing excessive. I had one or two pop loose after shooting through my layered target.
I now apply a drop of Duco to the leading and trailing portion of the feather.
I just shot through a deer Tuesday night with a taped, fletched, arrow. Complete pass through, got my arrow back in one piece. I washed, dryed and steamed the feathers back to good condition. Still attached...
I was having issues using glue. They seemed to let loose in the cold Illinois temps. I'm sold on the tape until I see otherwise.

P.S. My arrows are finished with polyurethane also. Not sure if that makes a difference.
