arreats + shaft works well too. Don't use fhr charms, they make little difference and if you MUST have fhr just use arreats + shaft, will give the same as 6 small charms.
I like using 18frw/22vita for teaming, and 20frw/20vita sc for against zons/sorcs.
Also, you really don't need many resist small charms on a barb.
I get 62 resistall from nat resists, +30 from anya, +30 from arreats, + 25lr 60cr from storm. I use 3x 11FR/frw and 3x11PR/frw sc + soul spurs vs sorcs and resists are maxed easily.

/w *thesuck for duels.
I use only legit but will be happy to take anyone on 1v1 in a friendly duel =)
