So. I have moved all my BTC off of my ARMORY wallet. I'm trying to extract the BCH from the ARMORY wallet. I'm using Trezor as my heart can't take anymore of this.

Should I 1st make an attempt of putting ARMORY into advanced mode and signing for the BCH.
Or should I download the BCH ABC wallet. Remove completely Bitcoin core including hidden files. Then install the BCH ABC and somehow point Armory to the ABC node?
