Who's extremely happy with theirs? What brand? First natural response when falling off bike is to throw your arms out to protect your head. Do that, and you end up with banged up elbows. I bought some fox elbow/forearm guards. But when I land from big jumps, they slide down to interfere with my wrists. These are the ones where the spandex straps criss-cross on my forearms. I had some really old ones that had a strap that went around my bicep for the actual elbow cup area and another strap around my forearm. Those never slid down my arm. I think they were JT. Also, I'd like them to not only protect the elbow but also much of the forearm and possibly fit under my jersey. When I look at pictures on the net or catalogs, I can't really tell what brand might be better than another. And no magazines have ever tested different ones. Any feedback would be appreciated.
