I can't believe I forgot to add this earlier, when I'm using lower power on a mech I like to use a "kick" it adds vv and low volt protection to mechs really easily. Cheap ones are limited to like 15 watts so.... Anyone fuck with micro coils, for ecig juice its about the same performance from a 2ohm build that one would expect from a good sub ohm. Not sure if its usable for oil though, micro means small like 1/16 of an inch so the wick has to be tiny it will have almost no capacity but it totally changes the way power is used. Micro coil is skinny wick with like 10 wraps ALL touching tight to each other so no space between each wrap, I have only tried near 2ohm but it works good. It really cuts the monster demands we put on the batteries without costing performance. Maybe a ecig only tip but I'm head over heels about it so far, loads of info out on the subject. Turned an evod/proT into a pocket fog machine.
