We put the gvl poly kit on a few years back and am very happy with it. Run it on a 9560 so also added the height sensing kit I believe from lankota, may have been headsight, don't remember. I just got done adding hydraulic deck plates and all new chains, sprockets, and tensioners on mine. Hopefully gonna see less header loss this fall.
