yeah I also read reviews about Yokozuna similar to those stated here.
1) because housing is stiff. Good for 2012 and older Sram shifting, particularly front.
2) also because of stiff housing, braking response is firmer, a good thing
However, the stiffer housing also means harder to route the cable, especially the brake cable housing as it is stiffer than the shifter-cable housing. Also, the stiff brake cable housing may push the brake calipers themselves out of "dead-center" position, apparently that's how stiff the brake housing is.
Also, like Looigi stated, the outter diameter of the brake house is larger than normal, so this may also present an issue too as you try to fit the housing into metal ferules and shifters, but apparently guys have found ways to still install them!
Having said that, I'd go with OEM cables.
