White tape has a texture and goes in the front of the hole. Black tape goes in the back because it is smooth. I typically drill my equipment to have just 1 piece of white tape in the front for feel nothing else. Working out a thumb hole is an art in many cases. Very few ball drillers do it for their customers and some do not do it correctly. Thus you have bad fitting thumbs. I see a lot of wrong pitches and oversized thumbs so that people can just get out of the ball.
