I second the opinion for dripping on a phoenix rba. Can't really argue for only 10 bucks. Other than that been using ikenvape carts, 510 platinums or 801 fusions in tanks, i think those carts are the same anyhow.
I will second the genesis style RBAs. I rely on the AGA-T and the Chinese clone of the Cobra (Chobra) as my best performing atomizers. That said, I still find myself going back to the Phoenix RBA for dripping, it can hold about 10-15 drops. With a stainless steel wick, it comes pretty darn close to the genesis style IMHO. What I am still looking for is something that gives me the flavor of dripping, but without the leaking or the mess. Need to try a bottom feeder, although the prices on the Reos and the reviews of some of the other brands keep me on the sidelines.
