Using the 28awg, to get more flavor, Try adding more wraps higher ohms and increasing the power, add surface area to the coil. OR twist the wire build a little lower, I'd start at the .5ohms, since you like the vape at .8.
Twisting wire by hand is easy..
Make 2 S-hooks from a wire coat hanger. Take a length of wire and tie the end to one of the hooks, Loop the hook onto something high enough for the wire to hang free, hook second hook onto bottom of wire loop, hang a weight, I use a pipe wrench from the lower hook, spin/twist wrench, spin till desired twist pitch is reach, slow let the wire back of till it stop self twisting. Remove from hook and wrap coils.
I usually leave the twisted wire attached to the tied on hook. I use this hook to hang a weight from when wrapping the coils to create tensioned NO squeeze contact coils and spaced.
