I'm ordering a Riva 510 starter kit, and they are out of the regular kind, but for a couple of dollars more they have some with a dual core. What difference does the dual core make in vaping experience?
I notice that the dual coils give a better hit with a bit more flavor. The only other carto I have tried is a ce2 though so I am not an "experienced" carto user really. I just use them when I go out of the house.
This usually means that one could get good vapor production with shorter draws (or more vapor with the same draws).
... however the problem is that it taps the battery power much quicker as it takes more current (amps) out of the battery.
Just a warning, dual coils (while awesome) are said to shorten the life of Riva/ego type batteries due to the 1.5 ohm resistance. Boge 2.0 cartos are great as well. Both duals and boge LR can be purchased cheaply at crystalclearvaping.com for cheap and free shipping.
Dual-coils are great. If you can get your hands on 1.25ohm dual coils, they are better than the 1.5ohm since you are using riva/ego (3.4-3.7 volt).
