I know this product line is all non-stick cookware; however, some pieces are described as having a "sear" surface and others are described as having a "slide" surface. Does that mean that there are actually two different surfaces, and when you buy pieces you choose which surface you want? Or, are all of the pieces both "sear" and "slide" (which wouldn't make a lot of sense to me)?
Now, taking this a step further, let's say I wanted to make pan seared halibut with a pan sauce -- I suppose I'd want to use a "sear' surface for the deglazing, etc. But, if I wanted to make pan roasted halibut, I think I'd want a "slide" surface. So, does this mean I'd need two different Calphalon Unison pans, one for each type of fish preparation?
