I would def go with eth zoded. You have amp + probably max (or close to) deadly strike from this/higlord/gores. You need raw dmg.
Seems that now you need some cb so i would make that a priority for offhand (last wish? :))
I have rolled today grief for 394 damage this season and wanted to use it as main hand and dredfang to offhand (mostly for amp procs).
But im new to barb.... decided ti give it a chance for the first time in 25 years hehe
