I'm a Louisiana Boy, Living in Long Beach CA. A good Cook needs a cast iron skillet for searing steaks, salmon, creating classic gravy's and making a good roux, and not to mention the best fried chicken ever! I bought a friend the 12 inch skillet, and the 14" skillet is for me. I can sear six fillet mignon steaks comfortably in a 14 incher. Here's what I do: Dinner for Six: A little olive oil and a pat of butter in the cast Iron skillet on a Hi burner.. get it fiery hot. Generously salt and pepper (6) Fillet mignon's, sear 3 mins on one side, flip steaks and immediatly place skillet in a 450 degree preheated oven for 8 minutes. Remove form skillet and cover with foil for 10 minutes....HEAVEN!! 
Merry Xmas,
