The fraliens can run single coil 5 wrap 3mm at around 0.18ohms on a mech tube.
Ramp up is pretty quick due to the ribbon wire.
Another good build is FRAMED STAPLES but they react very similarly to fraliens accept the fraliens have the wicking ability due to the alien wrap.
Something like a simple polished 3x26 has great production too.
There's just too many to choose from lol.
For example aliens as a mech I like 3x29n80/38n80 5 wrap 2.4mm 0.14ohms dual.
Or 2x26/38 aliens 5 wrap 2.4mm
For 2 core Aliens example 2x26 Clapton a piece of 28 in your wrap wire 34,36 etc stretch and wrap over 2x26 cores.
