I am fairly new to using an RDA even though I've been vaping for about 3 years. I plan on buying the Velocity V2. I would just like to hear feedback from other members as to why they still use an RDA and build coils when if they're cloud chasing there are many tanks that produce abnormal amounts of vapor like the new TFV12 Smoke tank. So what are the pros for you in building your own coils? I know this may sound like I am doubting building but I'm not. I just would like to hear people's own opinions and experiences with building and why they still do it.
