I am working on Salmon using Mr. T's recipe. I have wanted some of the Frog mats for years, so started looking for mats that would fit the grill grates on my SMO66. These things are darned expensive when you need 6. I did a search for grilling mats that fit my grill size. I located some at Bed BB. These are Yoshi, and are copper infused. They fit my racks perfect. and are $9.99 for 2. We will see. I have 8 filets on these mats and headed for the smoker.
