[Q] How to switch from Otter to Otterx topic

I have Rooted, Pacman 4.4.4 RC2, TWRP 2.8.02, FFF, Amazon Otter installed on my "Original" Kindle. Can someone help me with steps to take to switch to OTTERX? When I read through the directions in the OP, it is written for switching from Stock. Thanks for any help. Also, would switching to Otterx show much benefit?
