I use it on my One Stringer wraps with a drop of super glue front and back - partly for insurance and partly to insure no sharp point on the front of the quill.
Just came back from a 3-D shoot and had some positive reinforcement. I did what nobody else does and actually missed a hog. The arrow passed just in front of the chest, went through some closely spaced saplings and I thought it was gone forever. I found the arrow about five feet beyond the saplings lying sideways on the ground. The cock feather was cleanly sheared off, but the quill was still stuck firmly to the shaft. Can't ask for more holding power than that.
