This is just out of curiosity but I am wondering ... can anyone explain to me why some atomizers have such a light draw it's like sucking through a straw, others just about cause your head to implode trying to get any draw out of them and the 'perfect' ones are just beautiful? What is it about them that makes that kind of difference? The wick? The coil? Sorry - I should explain that I'm talking about the Ego T atomizers here. I notice that some of the spikes in the middle are a lot skinnier than other and the skinny ones seem to have the lightest draw to them. This inconsistency is one of the reasons I am thinking of changing to cartomizers or clearomizers ... not that they don't, of course, have the occasional problems too. But they do have the advantage of keeping your flavors clean! Anyway, thanks for any response to the atty mystery.
