Mid-Level Caster Robes

[crapulence]

What would be considered the better of these two mid-level caster robes?

Tolapumj - http://wiki.project1999.com/Tolapumj%27s_Robe

Froglok Bonecaster Robe - http://wiki.project1999.com/Froglok_Bonecaster%27s_Robe

Both can be had for pretty much exactly the same price.

Tolapumj = More Mana, but Haste is pretty much wasted on caster-types.
FBCR = Resists, but a little less mana.

Thoughts?
