I picked up an iStick 50W and a Subtank Mini this past weekend. At first I didn't like the Subtank Mini at all, it was too airy (I like a harder draw) even with the air control set to the lowest opening and the flavor was much different. I am using 24 mg Halo Subzero mixed 50/50 with 6 mg Uncle Junk's Honey Do. When I vape it in my Halo Triton, I get a very pronounced honeydew melon flavor and the menthol is very subdued. When I put the same juice into a Protank 2 mini on the iStick, the ratio of the flavor is much more balanced. With the same juice in the Subtank, then the menthol was very pronounced and you could hardly taste any of the honeydew at all. I was beginning to feel like I wasted money on getting the Subtank. Last night I decided to play around and experiment with it and set the air control to the largest opening. What a huge difference that made. While the draw is still airy and it feels like I am drawing it directly into my lungs (with the other tanks I was doing mouth to lung inhales, is this what they mean by lung inhales?) there has been much improvement in the flavor. The honeydew flavor is still weakest on the Subtank, but at least now I do taste it. I do find myself setting the power very low. With the Subtank using the 1.2 ohm coil, the iStick is set at 9 watts. I like the cooler vape. The Subtank is still not my favorite, but it'll do.
