I have been vaping my Magma with a 28g single coil at 1.3ohm at 18watts (smallest air holes, mouth to lung hits) and really enjoy it. I would like to try lower ohms around .5 with a larger gauge kanthal. I am aware of battery/mod safety, my question is what is the main difference between vaping 1.3ohm at 18 watts and .5ohm at 30 watts? Thanks in advance for the feedback.
