once again great advice for stock occ coil heads, but he is asking about the rba deck and using the prebuilt .5 ohm coils that come in the kit to install on it.And I know you gonna think I asking a dumb question
Are u sure it's a 0.5 ohm coil as the sub tank comes with two coils 1.2 and 0.5.
Lastly there is huge debate going on on various forums about the new vertical coil versus the old horizontal coil and burning on the vertical coil.
Maybe try and get one of each and see the difference for your self
Lastly I personally would switch to 60/40 or maybe thin drops with distilled water
