As with any tank wicking is the key. If your Boreas leaks, you may not be using enough cotton. Checkout the augvape boreas thread if you need any help.Well I got my Boreas a few days ago and I have to say that I much prefer the Griffin 25 over the Boreas. The lack of a separate juice Flow control allows juice to flood the coil which in turn spills out of the airflow when you open it and is one large hot boiling Drop. I don't notice much difference in flavor or vapor but the machining on the Griffin 25 I find to be smoother. I also notice the airflow is more restricted on the Boreas. My Griffin25 has top airflow but even with the top AF closed, the Griffin25 seems less restricted.
