On a couple of topics already raised:
1. I also used Benzoin when I used Hada Tape from the roll. Since I switched to the precut pieces, I no longer need the Benzoin tincture. I also seem to have no need to clean my thumb with alcohol or similar. The Hada Tape and the Vise thumb tape both stick so well.
2. I also used white tape in the back of the thumb hole, BUT I cover it with a piece of black smooth tape. The white tape is far too rough and could be related to the thumb tape rolling up at the edge.
3. Although I am a lover of Lane Masters bowling balls, I find the LM thumb tape to not stick nearly a well as the Hada and the Vise tape. I should try it another time, just to make sure.
