It's a scary route, Dennis did a masterful job on the FA. But when I did it, I put my full, fat body weight on several Lowe Balls in a row and they held.
And, here's the key for the "top" anchor. One option is to sit and use body position as Dennis and Clint did. I wasn't wiling to do that though. Instead, once I topped out and was comfortable on top, I told my belayer that I was off belay. I sat down, untied and then pulled up most of the slack. Next I had my belayer go around to the other side of the rock, I threw the extra slack to him and had him tie into the rope (same tie in as if he was leading). Now, with him as my anchor, I had him sit. I then cleaned the route myself by rappelling off the other side from where he was sitting (that is, I rappelled a single strand of rope directly over the route I had just climbed). I suppose I could have had my belayer tie the rope to a tree too, but it was quicker and easier to just use him as an anchor.
Another alternative would be for the leader to finish Jingus and then down climb the Ridge Rock 5.3 route, and, once on the ground on the opposite side of the rock from the route, sit and anchor the second as they clean the route by jumaring.
The key to these alternatives it to carefully think through the forces and directions of pull on the rope and on the "human anchor." It's not hard to safely clean the route, the method used is just not "orthodox."
