I've had good luck with Magic Carpet in the past, and have just started using it again. I have found that I get a better release if I put the rounded end at the top instead of the square end. Try both to see what works for you. If you are going to use it, I'd recommend that you put it in all of the balls that you use, instead of some with and some without. In my Saturday night league, after using a Magic Carpet ball for the first two games and bowling great, I switched balls and had problems getting a good release with my normally reliable and best fitting ball that did not have Magic Carpet in it. It felt like the thumb hole was now too big and I had to grab the ball which killed my release. Just food for thought.
