I don't know if the moving to sub ohm is so much a 'ready' thing.
The nautilus and protons... especially the kanger side, had so many bad coils historically that I wouldn't want to add a layer of frustration to a new vapor. I dealt with hat myself back in the day and it pushed me to either smoke or make a move to RBAs(which I loved) not everyone would like building so much. With the new line of sub ohm tanks the coils seem to hold up better, the airflow set to low would give a similar experience and the cost is down.
The way I look at it, a started mod and tank say in the case of the new person the other night, 30 for a mod, 30 dollar for a suntans mini, she can use thenaurflow as she changes her preference and if she wants to try rebuilding she only needs the tools and knowledge, if she doesn't wit to rebuild its not a biggie.
just seems to be a cost effective option over a long term, not to ,mention a subtank has the 1.2 ohm coils so if subohming needs preparation to be ready for, theres that.
About that 200w mod.... wanna sell it?
