I installed A Stok grate on my Blue Performer and did some burgers. I lit my mini chimney with the center removed, which worked great.
The only thing i would do differently is maybe light more charcoal and let the grate warm up more.

I've just ordered one of these grates from direct tools after getting a couple of the inserts at 75% off during the target clearance about a month ago.
Haven't received it yet but they look nice in your performer 1911Ron
