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, cantis and calipers (and road cable discs) are short pull but there's a bit of variation in that, with cantis you can adjust that a bit by messing with the straddle cable height, but best to throw them in the bin and get some mini Vs, regular Vs and MTB cable discs are long pull.
