I saw this thread and thought this mod would be great for me too. I ordered an extra cage and went about making the changes. EXCELLENT! Far more comfortable, far more restrictive, far less noticeable in pants, far less pressure on my whole package when wearing tighter jeans.
Thanks for posting this, I love it and the wife likes that there's no more movement inside the old 6000s.
BTW, I used SCIGRIP #3 solvent cement designed for joining polycarbonate to polycarbonate. It isn't a glue, it a chemical weld. The material melts into itself. Sand both halves as flat as you can to mate as tightly as possible, then with a squeeze bottle with a needle tip apply a thin bead of the solvent cement to the joint as you hold them together tightly and the solvent will wick into the joint all the way across the two pieces and join them almost instantly. I think I had about a 10 second window to make a small adjustment. In 1 hour I was sanding it smooth, and 4 hours later I was wearing it and wore it overnight. It withstood the boner test a few times during the night and then my wife gave it the ultimate test in the morning... All passed with flying colors.
