I have used hot glue (the same stick that comes with a hot glue gun) for a number of rods. I now use a hot glue stick that is made specifically for tip tops that seems to melt at a higher temp and does not go soft in hot weather. I live in Florida and have had several tip tops come loose when using the normal hot glue. I've always been afraid to use epoxy, but it may be the best bet for hot climates.
