I am wondering if anyone can suggest a good next level for me? I currently use a Joye510 PV with an Atty and a Joye 510 Mega Battery. Which I believe is 280mah. I have a friend who just purchased an Expert 510 Atomizer and claims it performs much better because it has a larger bridge and creates better wicking and tons more vapor. Box mods and 6 Volt PV's seem great and are definitely something I'd like to work up to soon. But I'm wondering if this Expert Atty is a good next step or if it's just a gimmick and I'd be better off saving my money towards the higher volt PV's out there?
