One characteristic of being too high is a grinding or rumbling sensation not noticed earlier running wide open.
No real noticeable vibrations from going up one hole, try the next one up and see if it performs better or not from the last.
The V's seem to like the bow a little lower than every other boat, don't judge them by others. They perform better almost flat instead of trimmed up.
This is a picture of a 20" transom and a 20" motor close to the best location. The cavitation plate is a little over an inch above the bottom of the boat. So don't be surprised of your adjustments.

My cavitation plate is just a little more than an inch above the bottom of the boat....so that sounds about perfect.
I never run with motor trimmed down.....always with positive trim...trying to get the bow up. In fact I probably run to much trim bc I cavitate in turns and have to trim down to grab a little.
