Truth be told, though, I prefer ni200 over titanium and stainless. They all do the same thing and nickel is easier to work with. The disadvantages of nickel are that it's a softer metal and is easier to break when building a coil (not an issue if you use prebuilt coils... and honestly, I've never broken a coil during a build) and that you can't build micro coils with it (not an issue for me, as I prefer macro coils). Titanium is springy and stretches back out, requiring torching during a build... bit more difficult to wrap, too. Stainless allows for micro coils, just like titanium, but it's a harder metal and is more difficult to coil than nickel (not as difficult as titanium, though). And it may be mental, but I think ni200 produces superior flavor to the other two metals. Never used NiFe30, so I can't speak to its pros and cons, but it supposedly has all of the advantages of both nickel and stainless, but none of thier disadvantages. We'll see, once it's readily available.
