Definitely same for me on the KFL, I have dozens and dozens of parts to make all types of configs.I never used the stock heads at all. I bought 3 packages of heads and still have 2 1/2 packs after all these years. I just kept on with the heads that came in the kits and bought 3rd party orings and insulators. Took the new coil and tore it apart then set my own build into them. I have no idea how many PT 1,2 and mini's I have but got several of each still sealed in their boxes. Same with Kayfuns, loved their vape and build variety(back in the day) so bought all kinds of parts and attys so I'd never run out.
The way the UK peeps describe the naturevape coil definitely makes the PT sound tempting. They are so cheap I might pick one up just to fiddle with.
