Epoxy is indeed very strong but also very heavy. Frankly, it makes little sense to have a bond stronger than the surrounding wood. I use it primarily in two areas - the engine firewall and the wing center joint. Everything else I can either use aliphatic resin (the yellow TiteBond or Elmer's glue) or CA adhesive.

One additional disadvantage of the CA glues is you can make a permanent mistake in a hurry!
