Baking Sheets

What kind of baking sheets do you use?  


Whenever I follow a recipe and it says, "butter the cookie sheet", I never do.  Why? you ask. It is because I have been using insulated, air bake, baking sheets for so many years now that I never butter or use parchment paper or any of that prepare the cookie sheets. 
In fact, I have had these same sheets for so long and never have had to replace them.  They clean so easily and don't get that brown/burned look either.


I'm actually afraid that if I return to regular non-stick sheets or the metal kind with parchment or silpat liners that my baked goods will not turn out the way that I like them.


I'm almost a little superstitious about it.


I want to try silpat or parchment liners but what if the cookies don't come out right.  It always seems that I am baking for an occasion and I don't have time to mess it up. :) So, I guess if it isn't broke don't fix it. Bake on.
