I know it has been touched upon in other threads, but I'm pretty confused about this note that appears in most of the listings for FSA chainrings:

Some are designed to work in specific tooth combinations; see specific compatibility at individual part number bullet point
S10 is compatible with Shimano, SRAM and Campagnolo Ultra Narrow 10-Speed
S9/C10 is compatible with Shimano 9 speed and Campagnolo C10 10-Speed
N10 is compatible with Shimano, SRAM and Campagnolo Ultra narrow 9 and 10-Speed

From this, I would assume that I want an S10 version, but the listings for the parts don't say anything about S10, S9/C10, etc. or how to order the different versions.

FSA's web site has almost no technical information whatsoever.
