I've been using the smallest GR10ABWI George Foreman grill and it works pretty good with thin patties. I bought a larger one Temp to Taste? Grill by George Foreman because I wanted more area. Now, the new one won't clamp down as closely and won't even touch the top of thinner patties like the frozen ready to cook type. Is there a larger area GF model that can handle thin patties like the GR10?
