I'm wondering why people like Tracy Crook and Bruce Turrentine bother with TES "O" rings. I think they may have a better idea - don't you!
 
You don't seem to be wondering why they DON'T use them on the outer O-ring :-)  
 
Seriously, you're absolutely right about this being appropriate for the list, and it's human nature to want to improve things.  Unfortunately, until it's proven with some hours on a flying engine, you can only hope that it will be at least as good as the stock ring, since they never fail.   
 
One good thing that came out of this thread for me is learning that Mazda went back to putting the o-rings in the rotor housings.  I hadn't realized that.  I did a check on the stock Mazda o-rings though, and note that there is a different part number for 74-85, and 86-95 (and later in other countries).  I wouldn't be too quick to assume the size of the Renesis seal, or the pre-86 seal will be the same as the one on the end housing that Kelley is sending Creavey.   
 
Enjoy your TES quest.
