Well, I was smoking 3 ppd when I got here, but I found I preferred a smaller device with higher resistance, mouth-to-lung, with less vapor but more flavor and more nicotine per puff. What you chose starting out was something more cloudy, typically running at lower resistance coil, higher watts, producing larger clouds of vapor that you inhale directly into the lungs (I think, depending on your coil). Some people prefer one or the other, or even both, or something in between. If you are going to warranty the mod, I'd probably suggest trying a MTL setup, they can be pretty inexpensive, you may find that you prefer them, or more clouds. One starter kit I would recommend would be the aspire zelos kit-- it's a small
tank (the nautilus 2) and takes coils that are of 1.8 or 0.7 resistance, and the airflow is much smaller. So you'd inhale that into your mouth, then into your lungs and out mouth/nose. It's fairly inexpensive, the kit can be either a 50 watt battery without TC or a 75 watt battery with TC, if that interests you. Very small and portable (and discreet) and you'll probably then be able to figure out what you prefer. The Eleaf pico starter kit with the Melo II tank is also a good place to start, and it has tons of coil options, so it's variable, also fairly inexpensive.
I'm sure others will come along with good recommendations, too, but that's what I might suggest.
Good luck, and I hope your mod is warrantied or repaired quickly.
