On the curveball DVD, you used two baseballs taped together when doing drills to teach proper curveball rotation. As I understand it, the product in the photo attached to my earlier post is designed to teach the same thing. I saw it in a store and was curious what you would think about it. Before spending the money, I thought I would ask your opinion.
My son (age 15) is just beginning to learn a curveball, and I thought this might be useful in teaching him the proper way to release it.
I know that you generally discourage the use of most training aids because they do not replicate the actual pitching motion. When teaching the curveball, however, especially early on, when you’re just working on rotation, would a device such as the one shown in the attached photo be useful?

Why would you use something else besides a baseball to get the proper feel of developing correct rotation?
What exactly is your problem with the curveball?
The two baseballs tapped together show you how to grip and release the ball.
But you only need to use it a couple of times to get the understanding of how the ball is released. Then you switch to a baseball.
Save your money. Tape two balls together.
Then, in order to make sure he is getting the correct rotation, you can color one side of the ball black so you can see that the rotation is more vertical than horizontal.
