Iroquois is exactly right. When Hoyt first used the design they apparently didnt understand how it was supposed to work because they let the cable float on the yoke which didnt allow independent tuning on each side of the yoke. The result was a lot of bent axles on Carbonite split limb bows because you couldnt tune out the lean at draw. Hoyt changed to the served yoke the very next year. The new system still allows them to get around the patent.
