I feel like wielding two one hadned weapons is to strong at the moment, since you add both dice Rolls according to the example.
When you find both d6 weapons, your councilor is basically invicible in a fight, especially if Jody alone, or with CJ in a cabin.
Therefore I will probbaly go over to a Variant, where you roll both weapons and take the higher of both rolls.
This is meant to retain Otis deadlyness when he is on high attack and to coserve usefullness of two handed weapons, wich are far inferior to onehanded weapons at the Moment in my opninion.

reroll of the butcher knife not tanken into account
After playing for the first time, I tend to agree that Dual-Wielding is too effective, and will probably be using the 'use highest die' method myself.
