Yeah, you may need higher voltage or 3.7v + LR atties/cartos.
Also, take some factors of juice into account. You can try higher nicotine content 24-48 mg. Certain flavors/additives in juice will have more throat hit (cinnamon, alcohol, pepper, menthol/mint, etc).
Did you mean that you wanted more clouds of vapor as well? That could be difficult if you're wanting more throat hit too. Some people like a ratio of 80/20 or 70/30 (PG/VG) to get both throat hit and vapor but I find VG diminishes the throat hit too much for me. PG will give the most throat hit/flavor but less vapor. VG will give the most vapor.
If you cannot buy a new PV right now I would recommend trying Atomic Cinnacide from Tasty Vapor. I haven't found any other juice that can compare to it as far as throat hit goes. I'm a bit of a throat hit fanatic so I buy it at 100% PG 36-48 mg. You could start with lower mg or a PG/VG ratio. A lot of people find it satisfying at 24 mg with 80/20 or 70/30. They sell samples too.
Either way, a better PV could potentially allow you to vape a more wide variety of juice.
Good luck!
