Scientist discover best Cheese Blend!

Just saw this article about Scientists at the University of Auckland testing different cheeses on pizza. They say a mix of Mozzarella and Cheddar gives ideal combination of texture and flavor! What do you guys think? If you blend your cheese, what type do you use?

The flaw in this theory is you get a different result from the same cheese when cooked in a different type of oven or at a different temperature or for a different amount of time or any combination of the three. I tried every cheese available to me from all the suppliers in the area before choosing that cheese that works best for me.

I do have pizzas that have a blend of mozzarella and cheddar but there are many customers that ask to have the cheddar left off and a few that want only cheddar. As with most scientifically derived theories there is a margin of error often related to human preference.
