I haven’t used them on my SmokeFire since they increase the temp a good amount. I love them on my Genesis, they are easy to clean once seasoned. I do use one of their brushes as it gets between the raised rails better. I have a third of the ones on my Genesis upside down so have a flattop like surface that is great for vegatables and toasting buns. I’ve been tempted to get some for the Smoke fire to used for higher heat cooks, but can’t decided if I’d want them for low and slow. Hopefully someone else can weigh in that has used them on the SmokeFire as I’m no help there.
