Goat Tuff is what I use and have had great luck with it, on alum. and carbon arrows. The pro shop that I buy from, uses a glue designed for radio controled planes. Not sure on the name but they claim to have great luck with it. They pay about $4-$6 for a bottle about 5 times the size of goat tuff. I think I will continue to use goat tuff though.
