I've been following the threads about it myself,.........

I don't know if I see the potential benefits outweighing the hassel of another mechanical device mounted on the bow.......if they aren't done JUST RIGHT it sounds like you'll end up with excessive cable wear, significant preloading on the limbs and drastic changes in tuning. Plus I'm hearing the need to keep oiled so it doesn't make noise.

If it evens out the and lessens the side load on the cams caused by the single cable rod that's a plus........but I'm not sold on the idea.

Not yet anyway.....I've definitely learned to never say never.
