Voile Switchback v. Switchback X2?

I kept breaking the area just behind the pins (toward the heal direction..) on my Merrill Super Comps ("leather") (costing me over $100 a pop for sole replacement and the Comps were over $500 new?..) and I heard that voile hard wires flexed further back than a straight three-pin setup and consequently would mitigate the breakage problem. That took care of the problem and so have gotten used to the cable so much that I've used them ever since with plastic.

Side note: I find my newish scarpa t-1s stiff enough that I don't really need the hardwire cable settup to make the boot operate from the ball and I still get lots of leverage (I still ski with the cable on though). I really like the cable though with my t-2xs as it does make those boots "break" further back for the active feel I've become accustomed to.

Think I will purchase the voile switch back sx simply because I've seen a few broken Blackdiamond cables
on the new stuff (and broke lots years and years back) but have never seen nor broken a voile hardwire.

Looks like voile will be plenty active, maybe more than the three-pin hardwire and maybe a tad lighter than the Blacks..
