1.8ohms - will burn hottest
2.4 - will burn second hottest
2.8 ohm - burn 3rd hottest and requires the most volts.

the lower the ohm head is, the lower the volts youll have to set it .. Saving battery imo.
1.8ohm will need around 3.4-3.7v
2.4 will need around 4.0-4.2v
2.8 will need around the same

Some people like a 3 ohm head at 5v ... I dont like using any attys over 4.0v .. distorts flavor for me.

experiment with the 1.8ohm head first. most popular and gives best taste imo. i dont use my 2.8ohm as it changes the taste on me.
