I'm know I'm violating forum etiquette but I'm going to post one more time.
As of right now, I'm not going to vote in the poll. The more I think about it, the more I come up with reasons to keep or kill every spell on the list.
I think a better poll or discussion is to determine what different spell effects/types/groupings exist. Once you have that, you can start plugging spells into the different categories. It's also entirely possibly for spells to exist in multiple categories.
Here's what I mean:
Fire: fireball, scorching ray, fire trap, resist energy (fire)
Protection: resist energy, shield, protection from <alignment>, protection from arrows
Knowledge: detection spells, divination, scrying, identify
Movement: fly, levitation, dimension door, teleport, spider climb?
Air: fly, levitate, fog cloud (water?), gust of wind
Traps: arcane lock, fire trap, glyph of warding
