I've heard of this issue before on the Rodeos. The mini disk that puts the screws close together ends up with a lot more stress. My friends Rodeos are currently stuck on his NS Revolver because multiple inserts in the board failed. His would loosen often as well. He just kept tightening them. Being a 230lb beer delivery guy I can assure you he wasn't leaving them loose. Talking with a shop guy while in Denver he had seen the same thing with the Ride mini disks. He suggested moving the screws to the normal square pattern. You loose some adjustment but it holds better.
