That 14 pound turkey looks like a cornish hen on a regular Performer, the cooking real estate it huge. And I really like your idea of the expanded metal keeping the coal off the kettle. I added some 1/2" expanded metal to my 26.75 OGT charcoal grate with great results, think I'll add a vertical like yours. Thanks for the idea.
Got a bunch of cooking toys and a custom metal fabrication shop where I spend my time building all sorts of smokers & outdoor cooking gear.
