I use Fletch-tite Gold seems to work fine a little more exspensive but what isen't today. Just a word no matter what you decide to use make sure you rotate the insert a few times to make sure the glue is dispersed equally arround the shaft or you will never get yur broadheads to tune properly. Also when the glue is drying leave the arrows virtical with the point down so it dries evenly and dosen't run even slightly to a side. Mike
