Specialist wizard variants, ala Un.Arc.

[Driddle]

If you're going to play a specialist wizard and are given the option of picking the appropriate variant substitutions out of Unearthed Arcana (collected here: http://www.d20srd.org/srd/variant/classes/specialistWizardVariants.htm ), which specialist would you pick, and which of the three related options would you apply?

Both the Energy Substitution Evoker and the Transmutable Memory Transmuter seem fairly fleible and useful.
