Hi, I used to install S&S couplers and I am familiar with the Ritchey connectors. Unfortunately you hit the nail on the head (so to speak). That is the complaint that I have herd about the Ritchey connectors is that that they not much better than a muffler clamp. No provision for twisting force. Back in 2006, I was making a connector prototype/ alternative and came up with this terrible idea of having overlapping tubes and using a seat clamp to hold it together and set screws so it would not twist/ separate. It worked for about a mile, but after that the twisting force was too much, and it started to try pulling apart, (back to the drawing board). Well, at least I did not get hurt. If you come up with a design, please be careful!
