Excuse my ignorance but could you please elaborate on mouth to lung versus... whatever the other one is called?I had the same issue of harshness from the Mighty, but in the end I actually attribute much of that to a relatively high vapor production. I had to switch to MTL for the Mighty to compensate which made a big improvement. IMO people do underestimate the power of the Mighty a bit, it can crush 200mg in like two good pulls.
Thanks
