well the only problem with waring heavy armor is that it creates a 40% spell failure rate best to stick with the lighter armor in which case you really don't need to multiclass unless you want to use all the different weapons. If you don't plan on, or tend not to use alot of different spells i would go for the soc. however if you want a wide veriety of spells to draw upon for different tackticks go for the mage instead, but thats just my opinion.
