Ok so sometimes I used a Mechanical mod like my sigelei with a protank that has a 1.8OHM coil in it. It works good but every so often I get a burnt hit and I have to blow it out to get it to taste better. Im guessing this is because The mod im using does not have a VV. So would I be better off to use a 2.2 or 2.5OHm in the protank?
