I've been looking at these for quite a while now and want to get a few. The only place online I can find a decent selection is here: http://www.finestcookware.com/catalog.php?c1=37&c2=250 As you can see, they offer seven different sizes. My only frame of reference is the two cast iron pans I have. One is an 8" and one a 10". I use them both equally and really can't tell if they would be the sizes I would want if I had other choices. As you can see, the actual cooking area (bottom diameter) does not line up with the pan size between cast iron and the carbon steel pans, due to the flare of the sides. The 9.5" carbon would pretty much equal the 8" cast iron, etc. Are there really any sizes that just get used a lot more than others, or is it pretty equal across the board? There are four of us to cook for, if that matters. Two kids, wife and myself. I'm trying to pick out three useful sizes and am just having a really hard time. There just might not be an answer to this one. I'm guessing the largest and the smallest might not do as well. The largest might have trouble on a regular size home stove burner. I don't know what I would use the smallest for. I have a really small cast iron in a similar size I use to brown garlic for different italian sauces. Now I'm rambling. Well, any input, opinions, etc. would be appreciated. Thanks!
