Kimsha Quick-Stick works really well. I have been using it for 10 yrs. or more. It is less brittle than Ferr-L-Tite, much stickier if you will. I wouldn't go the epoxy route as it does not allow for flexibility i.e. removal of the broadhead, JMO. I see in 3 Rivers, there is a new Ferr-L-Tite Cool Flex specifically for carbon arrows, it has a lower melting point, probably like the Kimsha, making it gooier/stickier.
All suggestions above will work fine, but for a hot glue, I think the Kimsha is a better choice.
Good luck!
