I customized an Excalibur for Tidus, since Caladbolg is so hard to fully activate, and not tied to an Aeon anyway. Auron's Murasame, Yuna's Nirvana, and Rikku's Godhand are relatively easy to fully activate, so I didn't customize for them.

I didn't do either for Wakka, Kimahri, or Lulu. Four characters with BDL weapons was more than enough to win the game in the U.S. verson.

Customizing is often hard to do, but I like being able to pick the three abilities other than BDL.
