Okay, here's what I can do about this:

I've got a Superbe Pro RD-00 that has more than enough throw for 8-speed, and a Cyclone 7000 I'd like to try; as well as an XC-D unit; Shimano RDX, 105, Ultegra and XT mechs; And a Sachs Quarz MTB rear derailleur.

Cogsets I have are Suntour 6 and 7 speed 4-prong; Shimano 6 and 7 speed freewheels; Shimano 7 and 8 speed cassettes; and Sachs 6 and 7 speed freewheels, both ARIS and LY 9x. I *might* be in posession of Suntour 8-speed cassette by January, who can say what the world will bring?

For shifters, I have Shimano brifters, 105 in both 7 and 8 speed; Suntour Command Shift in 7 speed; Shimano DT shifters in 6 and 7 speed indexed, and a set of 8-speed barcons; and I think I might have a set of Sachs DT shifters in 7 speed indexed but I'd have to check, I think I might have swapped those out. I know I have a set of Sachs pre-SRAM gripshifters but those are a PITA to mount.

Testbed would be my Trek 560. I can test Sedis, SRAM, KMC and Shimano chains in new or near-new condition.

Question: Have I missed anything, or will this be enough for a fairly comprehensive test of what works and what doesn't?
