Saw where you did post links to the o-rings and mount w/screw from geoman. I take it that the o-rings are the original mounting system?
O-rings ARE the original mounting system. There is two different sizes of o-rings, and they are normally sold in pairs.
This type of mounting is very secure, but it may slide little bit on the bumps. It's easy to adjust with just a push of my finger :-)
