dual
coils was tricky for me at first... u gotta make sure its the same length of wire on each wick.. and all the
coils are glowing evenly, i was able to make some nice coils and didnt have much trouble with the two wires @ the positive post.. but it turns out its not really worth it or that much better considering the battery drain to power two coils...
the issue i had was the coils werent getting hot enough unless on a super fresh battery (i have a mac350 as well), and the battery life was like 2-3 hours MAX
and i really didnt notice too much more vapor/thoathit. on just a single coil you get way more batt life and it hits just as hard IMO cuz it comes down to the temperature of the wick, not just the wattage.
