To update, I tried the caramel apple 80pg 18mg, no extra flavor shots, in my vivi with the 1.8 head on the gripper. 3v is giving me the best flavor from this. It's been steeping about a week. I'm getting some decent flavor from this. I will say that I gave the ecto another shot today in a ce3 bc that it's been sitting in for about a week. Quite a bit of th from it which was nice. The flavor is still shy and a bit odd, but will keep checking it. I normally get tremendous flavor from my ce3's and my vivi, so am sticking with using these for testing.
