Weapon Enchant - Berserking

Hey guys, just got my BiS weapons on Frostmourne for Naxx, Calamity and Angry Dread as an Enhancement Shaman. Was just wondering if the Berserking enchants stack for dual wielding, or if it's better to enchant something else for damage. Am hit/expertise capped.

Thanks

They stack, it's all good.

Oh ****ing pog, time to waste even more money
