I have the Stok grate and it works well and have itinstalled on a Gen 3 Performer. Bought a GBS this fallfrom the Palatine store and it's still in the box til Spring.What also works really well are the CI and PCI grates froma Genesis. They fit on a 22 perfectly between the hinged gratesallowing full access to ad fuel. They really make killer grill marks.
Anybody have any experience with these? https://abcbarbecue.com/product/custom-fit-grillgates/ThanksGMO
