Ok, what are the differences between the Ni200 and titanium? Resistence, taste, life of the coil ...
Never personally used titanium, some people swear by it, but keep in mind the DNA40 is programmed with the TCR curve of Ni200, so the temp setting wont be accurate, but by lowering the temp setting it will temp control properly.
Many of the newer chips (yihi j chips, joyetechs VT, DNA200 etc) come with dual modes for either Ti or Ni200, the DNA200 can be programmed to use nearly any wire with a 'workable' TCR curve.
I'm happy with Ni200 in my builds, though once i get my DNA200 completely built i may give Ti a try. Generally Ti builds will have a higher resistance, from what i've seen/read. Not sure regarding coil life, would assume it would be similar to or longer than Ni200, due to the wire being slightly more robust. Some people say Ti has a 'cleaner' taste than Ni200.
You've got a really nice set-up so, as they say, "If it isn't broke, dont fix it!"
