I do not have VV but use Melodyne instead. The secret... if there is one, is to do what has been said here already. Make small changes and it will do a fine transparent job.
It's when you try to make big changes that things can get squirrley.
I use my pitch correction on all vocal tracks regardless of how well the part is sung, and I do not hesitate to use it on instruments either if it is called for.
If you played a really nice inspired solo and grabbed the wrong fret by mistake.....it is an easy thing to fix the occasional wrong note in a solo.
