Also is there a good site I can order the
coils from? It seems difficult to find coils for the Pyrex smoktech
tanks
I'm curious. After just now looking at the replacement coil heads for this I wonder if a protank/evod head would fit it. They fit the Aro, and the coil head for the mbc fits the Aro. Just wondering...
Also I noticed that you said the 1.8 seems to give you a burnt taste and that the 2.5 is not. With the 1.8 heating up faster, that makes sense that your 2.5 isn't. I'm guessing you take a longer, slow draw. That's what I do and those ohm ranges gave me the exact same experience you're having. This is why I prefer the higher resistance.
Check out Discount Vapers and see what they have available for Smok coils. I got my first Aro from them.
