Looking at the picture....can you tell me where the holes of the coils are facing? Are the coils sitting perpendicular (as oppose to parallel) to the deck? A closer picture would help a lot. If they are facing that way....the length of the leads from the neg. post are either longer or shorter vs the leads to the pos. post. I usually try to have mine close to the same length. Also airflow affects your vaping experience TREMENDOUSLY. Having the airholes directly in front of the holes of the coils may not be a vape you like. Although, there are setups where it could be a good thing. Looking at your build, I don't think it's the vape you're aiming for.
