SRAM 1:1 and SRAM Exact Actuation are different. If one says 1:1 and the other says Exact, they probably won't work. In general SRAM 9 is incompatible with SRAM 10 (although there may be some odd bits that work together)
No, Yeah, I think the cable pull and derailleur ratio are different between 9-speed and 10-speed even though it's called the same thing. It's really as clear as mud from the marketing specs, but I think the Arts Cyclery article is correct.
