I would respectfully disagree with two of these recent posts. I can personally attest that my Fox pads don't move once I'm in them. The only hit I ever took between the elbow and forearm cups was my fault because I pulled them on too high. Forearm cups are a lot more useful/important than I thought when I bought mine, too.
Second, concerning the IR pads - IIRC they have very thin or no plastic in them, just closed-cell foam, and they aren't that thick. I watched one of my NC homeboys get worked in Scream Machine on the Green at 150%, and then swim Nies' Pieces. In addition to getting his tailbone whacked hard, he took a bad hit on his elbow from that swim, from which his brand-new IR pads did not protect him. I gather that these pads are pretty comfy, but for serious protection I would go with something that has plastic cups.
MTB pads are really designed for hits on hard stuff, and to slide off that stuff - perfect for creeking. With closed-cell foam, they won't carry water inside. I'd head that direction.
PHIL -- if you are out there you need to tell the masses about the power-engendering abilities of the Street Sport EXTREME elbow pads...lol And if you are out there you better return my call about Cross on Sunday...fool. "The perfect river, the perfect day..."
Join up, suckas.
