Ld, As I am sure you are aware, vaping works on a principal of watts. We also want to conserve battery power so they don't go dead in the middle of the day. If you are not on a mod, this is important. One way to help the situation is to optimize your system. Ohms Law is what you want to use to get the biggest bang for your buck. I = E/R (current = voltage/resistance) provides the current number in the power or watts formula P=IE. Now using you battery voltage and the coil resistance, play with the numbers to find a resistance that best suits your equipment and personal like or dislikes. To save you some trouble, in the I=E/R equation E and R are inversely proportional to I (e.g., E goes up I goes down; R goes up, I goes down). In the Power equation, they are all proportional (E or I goes up and P goes up). I find I get more flavor when I run a lower voltage and flavor is what I want. If you want big clouds you go with lower resistance coils. R is down, so I goes up and with I up (in the Power equation) P will be up giving you the cloud you wanted. But, P up, E will have to be there too.
One last thing. With sub 1.0 ohm coils, make sure your battery has internal protection. It will heat up.
