I've never been a fan of variety, just pick what works the best and stack it.

For me everyone was heavy armor (light is better early in the game but eventually gets greatly outpaced) and sword and shield. The amount of damage thought most of the game (with the exception of ultimate weapons) between 2h and shield isn't all that noticeable, and the amount of damage mitigation is. I usually carried around a ranged weapon or two and had some magic to deal with any flying enemies, which are quite rare.
