I too had problems with 5v initially, i find that by flooding the atty(not to the point where it leaks ya), i get nice and overall cooler vapor and easier on the throat.
However this sorts of defeats the purpose for some because the atty is flooded and they vapor produced will be lesser in terms of performance.
at this point of time i find my fav vape to be around 4.5v with a variable. 5v is too harsh for myself.
it is said people with normal PVs would take 5 sec draws and when converted to 5v Shorter and faster draws would be of somewhat the same volume. I find this very true.
End of the day, i think you should try out different configurations like what debb did. Hope you find your fave config soon.
5v just ain't for everyone, different people different tolerance/preference level.
