Flaws for caster

[flappeercraft]

Right now Im making a build made to be overpowered in combat. The build consists of Fighter 1/Wizard 5/Incantatrix 10/Abjurant Champion 5. For this build I would need 5 flaws. What are the best flaws I could take? Im thinking I should take loner, innatentive, loudmouth and insomniac. Any suggestions on what flaw I should change and for which? If you need to find the flaws I mentioned find them here
Edit: I forgot I cant link places with copyrighted material I took out the link

ixnay on the link. Forum policy doesn't allow linking to places that reproduce copyrighted material without the copyright-holder's permission.

Also, by the rules, you can only take 2 flaws; if your DM allows more, then great, but the default is 2 tops.

I'd really recommend against using loner for this build as there are much stronger things than a feat that you can get in return for trading away your familiar. Ex: Abrupt Jaunt (PHBII)
