Got an epic item thats grants me 1 spell per level with spell perfection. Confused, help me pick!

[Grayfeather]

So for awhile i have access to an epic item that grants one sell per level with spell perfection. Once i pick I cant change it but otherwise this is pretty freaking sweet. However I'm stuck picking spells as I have access to wizard cleric and druid lists (a mystic theurge with special access to druid spells). My MM feats are heighten, piercing, persistant, and about to pick up maximize. I already have quicken on rods.

Some thoughts:

1st: Charm person
2nd: Hold person or silence
3rd: Slow
4th: Confusion?
5th: Flesh to stone
6th: Disintegrate
7th: ?
8th: ?
9th: ?

Advice please guys, thanks.
