Has anyone tried using the cage part of the CB3000 with the rings and spacers of the 6000? About three years ago I bought a 3000 and it was a perfect fit for me. The only problem I had with long term wear was chafing from the hinge. I eventually got rid of the whole thing. Then about two months ago I bought a CB6000. The ring is infinitely more comfortable compared to the old 3000 one. The only problem with this one is the cage of the 6000. My cock doesn't really fit in it. It is just a fraction of a hair too narrow for my penis to move freely up and down the cage. In the 3000 there was just enough room for air to circulate through the cage. But perhaps I just didn't dry my cock well enough after showering, but I also couldn't ever get water or soap in there. Anyway, I'm rambling on...my question here is: Can you use the cage portion of the CB3000 with the ring and spacer system of the 6000? The only problems I can foresee are the guide pins not lining up and the spacers being shaped differently. If I could combine the two in one device...then I could probably be locked up for however long I think possible (or as long as a keyholder decides).
