You can't really go wrong with the DNA.
Also heard the vapor drag is good.
If you went for something else would suggest looking into something can run AF FJ or MircoSur SME software that I forgot to link above.

The more I been playing with this MircoSur software the more I'm really liking it.
It's does a good job allowing me AF and Escribe setting. Easy to adjust all the setting within the mod. It offers many extra things not available in escribe or AF. Worth a look if your mod can run it.
Altho it's not as good as a DNA chip it does a decent job of mimicking some of the DNA performance. You can pick up most of the listed mods above for a reasonable price.
I use stempod almost 100% time now on the wismec sinuous 80. Really been enjoy the small size portability of this small mod over my DNA mod.
Granted the stempod is more my travel vaporizer and for out and about. Now if was my main home vaporizer it be worth buying a full time DNA for it.
So far I really been enjoying this combo. Now with MircoSur software offering cruise, on mod settings and close to the DNA performance on a $30 mod I'm super happy.
If looking for a great little travel setup this is one I would recommend. Grab a wooden stem and you have a reasonably priced sturdy vaporizer. With out any glass not much other than mod to break. Can slip it in a pocket side light are handy. For camping, hiking outdoor use it can take a drop or two. Worse case I'm out $30 bucks for mod.
