I looked around the web for exciting videos on parallel coils, diamond coils, Clapton coils. This is for the future. Which atomiser out of these would have the best scope for exotic coils? The dark ronin geyser, the nucleus v2, or the cosmic innovations astron? Like the idea of the geyser and the nucleus v2 though would they have room for parallel coils of a proper gauge, especially the nucleus v2 with its removable vertical build. The astron looks a nice standard atty where quad coil is possible. Any space issues with the geyser? Particularly with the posts and Teflon guide?
