I think I only recruited 2 people: Wakka to help with Tidus in front (though Brother's also good b/c I think he's the fastest swimmer in the game BY FAR from what Ive seen/heard, I just didnt know this till my team was set and high lv), and I recruited an al bhed girl for my goalie spot (don't remember her name). I think she was one of the top 2 goalies in the game, but I can't remember. She had high shot and grab (or w/e the keeper stat is I forgot it's been so long) so coulda put her in the front, but her def/hp weren't as good as Wakka's so I kept her in goalie since she was already incredible there
