Didn't know that. Although upon further investigation, I don't think the difference in cable pull of 6700 levers compared to other STIs is as different as cantis are to V-brakes:
I've used a variety of brake calipers with 6700 shifters; 6700, 7800, 6600, TRP, SRAM among others. While there is a difference in the brake actuation cable pull, my experience is that it is so small and is more than made up for when I switch out the standard brake pads for Kool Stop salmon pads. I've experienced no degradation of braking performance in any way when using the above combinations.
Yeah, I don't know what's what, I just know that some models of lever will be shit with some calipers. I remember people having this issue when they introduced the 7900 stuff and that's why I stuck with 7800 caliper on my fixed.
