Help my legit barb

My legit barb does all right, but I think he's not as tough as he could be, was wondering if anyone had any constructive advice...
Barb set up for WW duels, barb vs. barb.
Gear is as follows:

Helm: .08 Gaze (Cham)
Sword: 297% CCB (Shael Shael Eth)
Shield: .09 Stormshield (40/15 Max)
Armor: 160/60 Max Sup. Balrog Skin
Belt: .08 String of Ears
Gloves: Venom Grip
Boots: War Travs
Ammy: Corruption Heart
Ring1: 8% LL +13 STR -Rare-
Ring2: 8% LL -Crafted Blood-

Base Stats:

STR--190
DEX--156
VIT--164
ENE--10

Charms are assorted max dmg charms and +life charms. Nothing very worth noting. Not very rich or anything, so anyone got some ideas that don't involve replacing charms with 40x 3/20/20's?
