Low res on a riva or other large battery 510 connector pv is good for lots of warmth, vapor, flavor.
I only use higher power things, rarely want a "cool" vape. If I want cool, I can switch to a higher resistance cartomizer or, in my case, adjust the voltage on my mod.
If you are leaning that way, the vapor pure riva kit, which includes some eliquid, is a very solid price.
The standard 510 batteries, while fine if you really have to have cig size, just don't have enough kick for me.
