I love the CPU4000, but I've only had it, and the Schutt/Adams XV-HDX. The CPU4000 is heavier on a scale, but feels much lighter when wearing it. I didn't get a chance to wear it this year in any game above 85, but based on that game it seemed just slightly hotter than the Adams, and I think it's more protective. I liked it so much I bought a second one as back-up (wanted to get it before they are gone), and I doubt I'll use the Adams now at all. I was thinking about using the Adams for younger kids, but the CPU4000 is just more comfortable to me, even though it's overkill for some games t
