So here's where I'm at...I've been vapin for bout a month on my first e cig the Riva eGo. I really love it with the low res attys, long battery life and haven't smoked maybe 5 analogs (I was a pack a day smoker of Salem Full Flavors for 6 years) since I got it. But...I've been really lusting over the Silver Vein Omega, and the Silver Bullet. I really want to try 6v, and also 5v. First of all what is a good mod for 5v vaping? Am I somewhat close to that using my low res attys? And last but not least, should I wait a while till I drop $140 on an Omega (it's like $29 for the 6v batts)...or should I go ahead and take the plunge? What's so much better about 5v/6v? I don't want to spend all that money and say "Eh it's a little different from my eGo, but not $140 worth." Help!!! Then again it just looks so damn cool in silver vein...
