I have seen a pic from pez's site that one side of nokon's wound steel cable should be cut to fit into 11spd shifters.
Q-FACTOR IS A RED HERRING
Loving the response from Yokozuna, Starnut! Thinking perhaps with 7900 cables under the tape they may have to reconsider! They do now list a Campagnolo version but it doesn't say 10 or 11 speed and stock looks patchy on a quick scan...
For anyone interested, this is the Pez solution with Nokons:
When I first received and inspected the cables and housing, I was impressed with the quality.
Installation was very interesting. I had read this post and several others so had some good ideas on how and what to do. The braided housing for the brake cables is very stiff. It is also hard to cut. I tried a Park cutting tool but it just crushed the housing. I ended up using a drill with a cutting wheel to cut both the brake and shifter cable housing. It actually worked well and once the housing was cut, I just cleaned out the cable hole and filed off the edges.
I used the ferruels on all ends at all points. The brake housing ferruels are silver and a little bulkier than the shifter ferruels. At first it did not appear that the brake ferruels would fit into the slots in the shifters but I used a flat headed screwdriver and was able to press them into the slots for a nice fit. The only real issue I had was the small section of brake housing that runs from the point on the back end of the top tube to the rear brake. I tried to cut a section of the silver braided housing but it was just too stiff to work in this section. The rear brake would not release properly because the housing was so stiff and applied too much pressure. I ended up using a section of the shifter housing and it works just fine. I do like the feel of the cables. Shifting is alot snappier and braking feels more solid. The worst part of the whole installation was trying to thread the shifter cables into the Red Shifters. Whoever designed the Red shifters should be shot.
Negative G's run great with these!
Also, I am running Negative G's without a single issue with centering, despite the stiff cable and the WW whining. I cut it the right length the first time. Does everyone not understand how to center these using an open ended wrench? The braking is far better than my old Ultegra.
BTW, I think some confuse lever force with braking power. Braking power can only be affected by brake stiffness and pad coefficient of friction. The variable of rate and mechanical advantage have nothing to do with power, only how much lever force you must use.

I see where you are coming from, but stiffness of the brake lines is part of the overall equation. For example, if your brake levers are hitting the bars, for whatever reason (i.e. inadequate caliper/lever/housing stiffness), you're not obtaining the full power that is potentially available from your brake calipers.

contact me, I'll set you up ith a set to try.

We have some Reaction sets out for testing on the Campy 11 group, we will have news up shortly about that.
think it would matter if i ran oem shimano cables thru it?
by the way, it's interesting to see the amount of flex in the yokozuna reaction brake cable housing when the lever's pulled vs. another brand. i have one bike with generic housing, and another with reaction. the other housing squirms & flexes. the reaction doesn't even move.
if that has a noticable effect on brake perfromance, i don't know. but, i would venture a guess that stiffer housing is better (less friction & cable play?), similar to why stainless steel braided cable is used in high perf. auto applications (brake line housing, specifically).
