Parallel single coils will give you a better ramp up and cool down. Also placement of the coil can be tricky due to the drip tip protruding into the chamber but try to place the coil up some so the bottom of the coil get some air, this will improve cooling. I've found if the coil is too low the vape stays hot.
With a clear cap you can see the coil in relation to the air slots, you can adjust your heat some by lowering or raising it to suit your personal preference.
