    Would there be any advantage if the current cam system changed to a static yoke instead of the floating yoke?

    Normally, when one talks about a static yoke versus a floating yoke, the yokes attach to the axles. In the AVS system, the yokes attach to the eccentrics, so I don’t think it is Apples vs Apples.

    If you are thinking of correcting cam lean by twisting the static yokes, I’m afraid you’d end up torquing the AVS eccentric bearings and cause premature failure. At least my dealer mentioned that a static yoke would likely void any warranty.

    If you are thinking of installing long axles and QCC’s to correct cam lean, then you won’t have a functional AVS eccentric.

    So I don’t see any advantage to a static yoke.

    FWIW, I have an old Browning dual-cam and I’ve shot both with a Static Yoke and zero cam lean, and with a floating yoke (pigtail arrangement) and it shoots better with the floating yoke. {#emotions_dlg.typotux}

    To tell you the truth gjarcher, I  don’t own a Mathews with that system, but was just wondering about the physics of it(yoke tuning). Even over on AT when people mention cam lean and how they yoke tune it out,  you never hear of an AVS system having cam lean that I know of.

    Bob Jenkins (Mathews)told me that there was testing done with static and floating setups when the system was designed, the extensive testing done found the floating design far outshined the static yoke setup for the AVS system.

    This is true.  Bob told me this a couple of months before he told Fatboy…{#emotions_dlg.mathews_thumbs_up}

    …  you never hear of an AVS system having cam lean that I know of.

    Well, yes one does … not too much any more that Mathews tightened up the QA on the limb deflections … but if a split limb AVS system has unacceptable cam lean the fix is to replace the limbs with properly matched deflections.

    There was a recent post where the cam lean was so bad the bow must have been a pretzel. I don’t know if it was a limb deflection problem that got past the factory QA, or if somebody had bent the riser in a press. Either way, Mathews will fix it up for you … which is my “El Numero Uno” reason for owning Mathews. I’ll spare you the horror stories about PSE and Hoyt Customer Service … then again, someday I may decide to vent.{#emotions_dlg.mathews_brick_wall}
