I like tape, and I like about 4-6 pieces. I only use the white tape. 1-2 pieces on the front of the thumb hole, and the rest on the back. I do use the Vise Hada Patch precut tape on my thumb as well. I like my thumb holes pretty tight, compared to most people. That's just how I do it, it is up to personal preference really. Some of the new tape is pretty rough texture wise. A lot of the tape is made in the same place for the different companies. That rough tape is taking some getting used to.
Just remember, tape is your friend, don't be afraid to change it out regularly, and keep your thumb hole snug, so you don't have to squeeze the ball to hold on to it, let the ball hold on to you.
