I have another question about the lavatube I just purchased. I guess i should've listed them all in one post, but more questions keep coming up the more I research it as I wait the 2-3 weeks for delivery. I've read to get the full 6v from the lavatube, you need a higher ohm head. Will my protank 2 at 2.2 ohms suffice or do i need to stick above 3.0 ohm? What are the benefits of higher voltage and resistance if the amps are the same? I believe the lavatube I ordered was of the young-june variety if this helps.
