Default Busted fins

A couple of weeks ago I launched my Goblin and when it came down one of the fins busted loose. It actually tore off the paper tube and was not broke.

So I repaired it with some Titebond figuring that would fix it. About a week later I flew it again on a C6 3 and the same fin busted off again! Although one of the two streamers came off in descent. But still the same fin?

Also the same day I launched a quite old Baby Bertha. It had been in 'storage' for about 4 years. When it came down two of the fins broke. The glue joint held but the fins broke along the grain. Was that because it is old and the balsa is dry and brittle?

Anyhow, some tips on this kind of repair?

Would epoxy be a better choice?
