I was a fan of the glue sticks that Martin sold but are no longer available. I have 2 left that I only use for broadheads. A few years back I did find a source for commercial hot melt sticks used in cabinet making, on here I believe, and they work great. I have never pulled a trip off, even after shooting into a frozen bale. Both the Martin and the commercial sticks are an amber color. The commercial was rated at an incredibly high PSI and had ring grooves in them to be run through a professional heat gun. Hope that helps.
