Im reading a lot here on sub ohm'ing and the nautilus tank and how you cant do it. I have to say that I have been using the Nautilus tank with a Aspire Triton mini .15 coil for 6 months now and have had no issues! So, not quite sure what the issue is with doing this? Am i missing something here? Any thoughts? btw, using an eleaf iStick tc40w at around 420 F.
