I would like to add a comparison between the Dynamax and the One Fit Wonder V3. I was skeptical, but after using both of them (they are sitting side by side in my garage right now) I have to say that I favor the OFW V3 just a little bit over the Dynamax, and that surprised me. The outer coverings have the same feel, and they "throw" the same during wall ball shots. The difference seems to be in the "catch" for wall balls. The V3 seems more balanced. The Dynamax is slightly harder to catch. It's difficult to describe why, other than to say that the Dynamax feels like there's thick gel inside that sort of sloshes around in slow motion when you catch it, and that makes it feel off balance. I still am very happy with the Dynamax ball, and their durability is impressive.
