I usually use Two Little Fishes Epoxy Stick in conjunction with Glue and never have any problem. Basically, Coral glue-epoxy stick-coral glue then the frag.I use JB Waterweld and then just super glue some sand around the epoxy to blend it in. I am terrible with gluing frags to rocks. I lose like 50% of my corals because my snails dislodge them and fall behind the rockwork.
Also, do the same when I frag and work really well. Especially for SPS; seems to heal and encrust faster.
