Background: I have been vaping for a few years, I have used Protank II up until now. I decided I should grab another one in case my current one breaks, only to find out they are discontinued and most sites don't stock them anymore. Although I did find sites that still have them, I feel like I am holding onto an old design for no real reason. So I did some research to find out what newer RTA might suit me. The trouble is there are too many. I have no experience with any of them and I think what people are looking for is so different from me it is hard to take anyone's suggestions. I smoke MTL with relatively high ohms (2-3). My ecig is a nicotine delivery device to keep me off cigarettes, nothing more. I smoke a lot, like all day every day if I can. This is why it is so important that I stay off burning plant matter. Don't want: I do not care about big clouds, I do not care about flavour. Actually I do care, I smoke with no flavourings, just VG and nicotine. Ideally I want an atomizer that delivers the minimum flavour so I cant taste any sweetness from the VG. This is not a big priority though. Do want: What I do care about is price. I want to be able to build my own coils and I want them to cost next to nothing. I also want the build process to be as simple and quick as possible. The ability to have multiple coil housings so I can build several it a time is also nice, as opposed to building directly into the atomizer. It would also be nice to have a design that maximizes the life of the coils so I don't have to rebuild as often. I don't know what factors contribute to this. A question about wire: In my research everyone seems to be using fancy clapton wire. At first that seemed like a real obstacle until I realised that I could easily replace a clapton coil with bare wire in any mod that usually has them. On the other hand I don't mind getting clapton wire if the price difference is low. As far as I can tell the main purpose is to enhance flavour though so I don't see the point for me. Is my understanding correct about this?
