So I just made my transition from Blu to Lavatube (L-Rider brand) a few days ago. I found a local retailer and I was able to go in and get my entire kit. My question is in reference to my dual coil tank. I am not sure of the brand of the tank, as the lady who sold it to me wasn't sure either, but from browing online it looks like a standard 2-3mL DCT. I currently have it filled with some mocha juice, but recently picked up my second flavor, Mtn Dew. At the store, she told me my best bet was to buy a new tank for each flavor I want. This is because the metal tube in the center holds a good deal of liquid, even after the tank has been dumped out, and I would experience a signifigant flavor bleed. My question is: couldn't I just buy a replacement tube (cartomizer) for each flavor and re-use the same tank? Thanks in advance!
