Insulated Blanket for Pellet side on Pro Series Combo

[TJSlayer]

Hey guys was just wondering if anyone has tried a blanket for the smaller Pitboss on their combo yet. Mainly interested in just using is on pellet side and it's size is just under 600 sq in, so was thinking that the blanket for the 700 may work? Anyone have both or access to them to try? Or anything else that has worked?

I already have a welding blanket that I can use as well but looking for something a bit neater / nicer

Thanks
