Hi,
I like to compare this with motorcycle racing, because one of my brother used to race. He was very good, but the problem, whereas every racer had the latest new motorcycle, he could only afford 2 or 3-years-old used ones. He could drive as professionally as the first ones: trajectories, braking, acceleration... he had good experience and was much better than the average. But the latest motorcycles were always providing a better braking, a better acceleration, a better suspension...
Back to our flours: you can get a good-to-great result out of almost any flour, but when you use a flour that is specially designed for your use, then it will be better, if not much better!
