This raises the stainless steel toe box about 16 mm. and thus elevates your stance. The combination of the elevated stance and the narrower profile by eliminating the exterior cables reduces the chanes of winging out when it's mounted on narrow waisted skis. Some bindings have pins, some have only cables, and some have both. Voile offers the most selection. You can have just pins, just cables, or both on releasable or non-releasable setups.
Cables offer more control and are especially nice for softer boots.
Cables without pins are simpler to get in and out of since you don't have to line up the pin holes. Cables with pins have the advantage of a choice. You can leave the cables in your pack for the uphill climb and not have to monkey with them till you need them. Once I was on a trip where one skier's binding broke and we rigged it with a spare cable. Cables can abrade boots and increase the overall width of the binding's profile.
