I'm sorry it won't let me edit anymore Please add to my previous post - Sorry! Is this the right cart for PureGold? http://www.fasttech.com/products/1411/10004692/1458103 Is it 2.4 ohm I need for all carts and attys (omicron, ce4, and skillets)? Looking at commercial packages it seems like a VV 650 mah might be enough for me. Or do you recommend skipping the vv? I never worry about getting too little heat on my present pen. I see fasttech with several that fit my description but they are super cheap. These are OK to go with, right?
