I used to foil my GMG Jim Bowie, which was a pain because the drip tray was difficult to remove and replace. When I got my Advantage, I decided to try not foiling and it has been great. I just hold the insert and the tray over a garbage can and scrape away.
I, too, use the upper racks for cooking when possible, with a foil tray underneath, sometimes just fold HD foil into a pan to catch drippings.
I liked my Jim Bowie, I love my Advantage!
