Best route for farming xp

Hey guys. I've been running the Alkaizer run to farm xp. For those of you whom are unfamiliar this starts by running

Core of Arreat backwards, followed by

Tower of Damned 1

Arreat Crater 2

Keep level 2

Bridge of Korsikk.

I'm wondering if the boards before the keep are as efficient for an archon wiz as they are for a barb. Would it be more efficient for a wiz to run the keeps then bridge for example?

I appreciate any advice you can give me.
