is there any reason the boge cartos would be better than my volt cartos? I just don't get much flavor from them
Filler, wick and atomizer placement may be slightly different, I haven't felt the need to tear open any cartos yet so I can't answer that definitively. That being said, depending on the resistance of the standard Volt cartos (likely 2.5-2.8) stepping down in resistance will raise the temperature of the atomizer, vaporizing more juice giving you more vapor and better flavor.
As far as which cartos to get, remember that Volt is 808 threaded, so you need to either pick up 808 Cartos (I know LF has 2.0 808 Boges, not sure about other places) or pick up an 808-510 adapter. You can pick one up at GP PV Adapters along with the 2.0 Boge cartos swedishfish mentioned.
