Yes, JC might not be good for her b/c they are a little on the sweet side (and I add additional sweetner b/c I love anything sugary)... I have tried some of the virginia cured flavors and they are not sweet at all, blech! Therefore, she may like them. FreedomSmokeUSA has a very good reputation and do not put any sweetners in their juices unless you ask for them, they also have a very wide variety of tobacco flavors.
Equipment is probably okay. I found a little trick that I use when I want to hang one of my ecigs outta my mouth. I use the hard plastic mouthpieces that are not round (they have deep grooves and a lip which I can put between my lips or teeth). I think they are referred to as whistle tips, but they have to be hard plastic, not soft rubber (the hard plastic are stiff enough to stay put but the rubber ones slip out and the ecig falls down...). My hubby has even commented when I was able to hang my XL eGo outta my mouth. Go figure. To give you an idea of what they look like, here is where I have ordered mine from:
Modern Vapor. It is in the upper-right of the product picture. This particular one
will not work on the Volcano products because their attys are at a different height, but it gives you an idea of what shape to look for. I don't see any whistle tips available from Volcano, but perhaps one of their curved drip tips could serve the same purpose. Because the Magma is compatible with a 510, you could get some 510 attys and whistle-tip carts and be good to go, but not sure from where, maybe someone else has a suggestion on that.
