Raistlin predates that sourcebook, and many of his signature spells don't fit into any of those schemes. (It's one of the many reasons I dislike how they ended up handling magic in Krynn).
What are Raistlin's signature spells? Fireball, Featherfall (through his staff), Web, Charm Person.
He's a generalist wizard, interested in all parts of magic.
(The correct answer: "He's an AD&D magic-user"! )
