I have now read 210 pages of this thread. I have seen a lot and compiled a lot of good information. However, I am still unsure about the best basket size. I have seen a lot of different sizes. I know there is nothing set in stone but does anyone have any advice on this? I have a brand new Weber grate for a 21 1/2" grill that measures 17" in diameter. I would like to use it but it looks a little big to me. Any advice would be appreciated.
