This is a really cool mod for indirect cooking! Have already used it several times for that.
I had hoped to use it with my KettlePizza but it doesn't sit far enough back against the inside of the bowl. Using the tombstone / SnS combo I can just push wood off the back of the tombstone and it lands on the coals in the SnS. With this basket if I tried that it would wedge between the curve of the basket and the inside of the kettle. Also puts a little too much heat under that back edge of the stone. Bummer since I bet the openings on the flat side would keep temps under the stone a touch hotter if it just sat a little further back.
