Wiz17/Barb3 or Wiz17/Fighter3?

[XieJon]

Im planning to make a battlemage, but I dont know if either the Barbarian/Wiz multiclassing would be better or a Fighter/Wiz, because the Barb gets more hp and DR, but Fighter can have proficiency with (pretty much) everything, and tower shields. Right now, im a lvl 13 Wizard with an AC of 27 +2, 16 STR, 16 CON, 29 INT, 9 WIS, 9 CHAR. I have a -10% spell failure on light and medium armor, and currently having a +4 twilight heavy wooden shield, and a +5 twilight chainmail of power III. My trinket is a dusk heart, my wep is a +2 metalline longsword of deception, my boots are feather falling boots of tumbling, rings are reaver's ring, and chaos band. Saves are 11/10/9. My helm is Minos Legens.


I know im wearing the wrong things for a caster, but...
