So I am brand new to vaping. I saw an ad for a blu cig the other day and began doing some homework, trying to find out what the buzz was about vaping and electronic cigs. Yesterday I put my order in for a Joye 150 because it seemed like every forum and review I had read highly recommended it. For the price and the customizability it seemed like it was a very good investment. I also read up some about cartridges and cartomizers, but have a few questions still. I plan on dripping into carts but I was wondering if these disposable cartomizers had hidden benefits. Can you pack filled cartridges into a PCC? Say I want to drive around with my 510 and have a spare cartidge in my case, can I already have it filled before I load it? or do you have to drip the juice every time you plan on changing cartridges? It appeared to me that cartomizers allowed you to pre-drip and everything was cool there, just curious if its the same for carts.
