While many posters here use scales, and I am addicted, I think you will benefit the most from using scales since the volume may change based on how finely you mill the flour, while the weight will stay the same. I have done a lot of comparisons with various combinations, but I have been so all over the map with cold fermentation vs room temp, pizza stone vs steel plate in oven and in bbq grill, and electric pizza ovens, ischia v. yeast, I haven't drawn any real firm conclusions, though in general I like a mix of white and red berries, usually around 35% or more, up to 65% white hard berries.
