I would recommend the EVOD. It has a smaller replacement piece that screws into the bottom as opposed to the whole bottom portion like the T3. But, the T3 will make a good stepping stone. Be ready for some serious flavor and vapor. The throat-hit is so/so, but that also depends on what type of
juice you're using. The weaker throat-hit is one thing that all bottom coil clearomizers have in common. But, they are also a lot more leak proof and wick MUCH better than top coil clearomizers like the startdust.
I wouldn't recommend carto
tanks either... unless they have a fill port. Otherwise, you will have a lot of heartache when it comes time to fill them. Carto
tanks are good, don't get me wrong. It's just they can be finicky if you don't push that cartomizer back in just right.
