That.Wicking is more important for tanks than getting a perfect coil, let alone the tank itself.
Inconsistency is often the result of one side having more or less wick than the other. Dryness is often caused by cotton being in the coil too tight, and flooding often caused by the end of your wicks being too short or thin. Work on the wicking some more and you will be very happy with the tanks you have now.
Speaking of which, please post a picture of a build you have and people can chime in with some suggestions.
