Do NOT choose a particular school.. AND when it asks "what type of wizard".. make your own.
Choosing a particular school provides an extra spell slot at each level - Good. It however ALSO removes the ability to cast spells from the opposing spell school - *VERY* BAD.

The basic premise is sound, but the execution is flawed - it appears that you can't get any Auto Still feats until at least character level 24.
