Many players wrap several basic grip bands on top of each other. I advise against such "tennis grips". It becomes too thick (spongy) and you lose feeling for the gripform.
I personally prefer to wind up to the top where the grip strength rejuvenates. This allows a more flexible grip height and a good handling for the thumb grip.
