Hey. I've quickly glanced through the thread, but I've yet to find a suitable answer. I have 2 IGO L's, but they each look different, not only that they each perform VERY differently (to me anyways). If you notice, the top-cap on the left is angled.
The one on the left has better flavour by far compared to the one I have on the right. I've built 20+ coils for each, and the one on the left is better every single time. I want to purchase another, but I don't want to get another one of the ones I don't prefer. Am I crazy? Is this possible? They're both drilled out to 1/16th. Here is a picture.
