Keep in mind, if you are not vaping all your liquid, 3 drops may actually be too much. Usually a little gurgling tells me that that I am flooded, and I blow out about ten times in a paper towel, and add 3 drops if you do that often enough, and pay attention to how many draws you are getting, you will eventually get a better feel for when you need more drops, but before you get that dry atty nastiness.
I use a LR306 on my ego. They are a dripping machine. Its impossible to flood these babys. And the the vapor, flavor and TH is totally awesome.
I use the joye brand, but there are others out there. They are only for dripping, so make sure to get a drip tip, otherwise you cannot drip with the cone (you can, but you have to remove the cone each time you drip)
Try them and you wont be sorry.
I forgot to add that mine leak a little too, but I have found a broken in LR306 leaks less, either that or I am just getting a feel for them.
