totally depends on what volts you want to run....
I would stick with (max original heads)
1.8 at 3.7v 2.4 at 4.0v and 2.8 4.4v
But I rebuilt a head at 2.4 ohms with super thick wick and I can get it to 4.6 volts comfy
OH and best method. Take the metal cap off, take the
tank off, leave the post and wick on the PV. Take the rubber condemn off and put a drop of
juice on the coil, put a drop on either side of the metal post on the wick also. Re-assemble and fill the
tank. Give it a few moments to soak in and vape away (priming the wick is what your doing...)
