Ideal Voltage for a 510 Mod

[maskgeek]

I am getting fond of the 510 atty as it heats faster than the other attys. I would like to make a 510 PV mod and would like to know what is the ideal voltage that would be most suitable for the 510 atty.

Would it be the normal 3.7V, or 4V, 4.2V, 4.5V, 4.8V, 5V or more?
Do some of you use a 5V USB passthrough with it?

allot of people say that 4.5 volt is the sweet spot, others like 5 or more. it kinda depends on the user. i like 4v. some said using more then 4.5 they get a burn taste and a really harsh kick from it. but again it depends on you.
