I've tried ni200, making claptons was essentially required for vapor production, often older coils would hve to be all but submerged to fire. Currettly using Ti01, even coil sizing is an absolute must, much lower guages available for builds, now addicted to claption build. dirty coils can end up with the near submerged reuquirement, verry little flavor interference. I have some Nife30 from the UK (stealth vape) sofar it feels good like Ti, and the building was easy enough. I will say the break in time was a bit of a downside. not sure about stainless I've heard some rather damning talk about flavor.
