Yes, if you get an eGo/Riva kit (which I do recommend) then you can add a low resistance atomizer to your cart and a drip tip and this will mimic vaping with a higher voltage e-cig..
Electronic Cigarette - Starter Kits - Riva 510
Low Resistance Atomizers - Joye 510 Low Resistance
Mods - Drip Tips
This will help a heavy smoker quit smoking and switch to vaping.
Drip tips replace the cart/carto on the end of the e-cig. With a drip tip you can drip 2-3 drops of e-liquid directly into the atomizer and not have to deal with carts or cartomizers. Drip tips eliminate the middle man.
Also: the passthrough is super-cool:
Electronic Cigarette - Pass-throughs - Joye eGo
Thanks for all your great advise, I opted to get the ego, with lo atomizer. I love it,
Have any of you ever tried "pink spot vapors" if so what do you think about it?
