I just got the electrolux induction unit for my remodel (which won't be done till end of sept) and would like to order some nice cookware (only ever had cheap stuff before). The largest "burner" is 10" - In the line of cookware I am looking at the fry pan is either 9.4" or 11" - which is better? Would the 11" not work as well as the 9.4"? Is the measurements for pans the bottom or the lip?

Thanks!
