did you ever try .214, I'm thinking about trying it since Ikream 2.0 is built to use it, and that is what I'm running right now.
I make it a thing to reboot every other charge cycle, just have to remember to fire up LTE OnOFF and make sure its on CDMA auto PRL after each boot up (no 4G here yet, and even then I would leave it off unless I needed it)
Not yet, but maybe that is the golden answer. I have been contemplating myself.
