Even with a Sony VTC3, VTC4, or LG HB6 30amp, I'll suggest look at 0.25 minimum on your resistance as you'll still need some "UHOH!" room. If you are just starting out rebuilding 26 or 28awg thickest wire until you get the hang of things in the 0.6 to 0.8ohm range. Cartel is a nice mod, I've got an Authentic Brass V1 I've had almost 18months now, one of my favorites with my brass Nemesis Clone my second favorite mech. RDA really doesn't play an effect when unregulated, what they affect is flavor and airflow which can affect vapor production, but those only come after the coil, wicking, and VG content of your juice.
A lot of variables go into it, basically have to look at large or turbulent you want the perfect storm going on inside the the RDA chamber, looser airflow will decrease flavor, tighter airflow will promote flavor. I am like Ryedan, my RDAs I am a flavor chaser, 0.5ohms or higher, though when I was rocking my Cartel at first as my daily driver at work at a vapor shop I was a cloud chaser. I've been across the most of the spectrum, from cig-a-likes to cloud chasing at both ends of the extremes, even playing around with goofy coil designs when I was bored at work at the shop. Since stepping out of the vapor shop scene I gravitated to in the middle, most times on tanks and low wattage, mid-range wattage with TC and most my drippers, though I still do have a couple clouding setups (Mutation X V2 with a pair of Clapton Coils on a Sig150watt)
Just be safe out there.
