Thus far I've only used eGo batteries with T2, Stardust and SplitFire tanks (and a few cartomizers, but not really for me). Anyways since I've got a small amount of soldering/rewiring experience I figure it shouldn't be terribly difficult to move in to building my own wicks and coils, and it seems simple enough from what I've read so far. I am, however unsure whether I should start with a Genesis-style or Phoenix-style piece to work with. From what I understand the biggest issue with using a phoenix-style is the need for constant refills, yes? And are there any notable downsides inherent to Genesis-style attys? Thanks
