Thanks, much appreciated advice, I have looked into each of those tanks and they do sound more beneficial to myself than a DTL sub tank, in terms of reducing battery usage as well as e-juice, and more for flavour rather than vapour. I am considering purchasing one or two of the MTL tanks mentioned if my current one doesn't cut it. The capacity isn't much of an issue, I just think I may need a tank+coil that doesnt consume juice rapidly, which what I've read and what you have mentioned, an MTL tank does not. Speaking of e-juices, that's likely to be my next adventure as there is an endless amount of flavours and suppliers out there, may even take months before I find a favourite! No knowing what flavour I like until I've tried it. All part of the experience. Currently I have Blue Raspberry. I also have Candy floss, Bubblegum ice cream and a apple/pear/strawberry mix ready to try. All which I bought from retail with the mod but will likely buy my next online from a vendor from the e-juice thread on here.
