Re: [crwper] riser hardware?
It's called RW and a number (the RW stands for Relative Workshop, which is the original designer/manufacturer of the 3 ring system).
The RW10 and RW01 are both large rings, if I remember correctly. One of them (I think it's the 10) is slightly thicker and beefier, and intended for Tandems. The other is intended for skydiving rigs. I think the RW8 is the small ring. I believe they get designated with and S at the end for stainless, so the RW8S would be the bottom piece on a small stainless 3 ring assembly.
If you want to know for sure, give Rob at Morpheus a call. He's the one who explained this all to me several years ago (so no fault of his if I can't remember it exactly right, and screwed up the numbers).
